A few customers have an MSI installed on their system (servers and desktop's, winxp, win7, server2k8r2, server2012r2).
The MSI is created by a default VS2010 "Visual Studio Installer Setup Project".
There are 2 reg keys created with the installation.
HKLM\Software\Microsoft\Silverlight\AllowElevatedTrustAppsInBrowser = 1
HKLM\Software\Wow6432Node\Microsoft\Silverlight\AllowElevatedTrustAppsInBrowser = 1
When uninstalling, on some system's, the whole Software\*\Microsoft node gets deleted.
Anyone got an idea how I can solve this, without crashing the systems.
(This already happened a few times, but there are still a lot of installations.)
The zip contains an exe that install's requirements + certificates + MSI.
The MSI itself is in the IG folder.
There is also an install.log & uninstall.log (from windows 7 virtual box)

This reminds me of a similar incident ( using InstallShield instead of VS but both create MSIs )
InstallShield 2008 HOTFIX: COM Extraction Causes System Corruption during Uninstall
Your question isn't directly answerable given the information. I would need to evaluate the .MSI looking for custom actions, registry table entries and any self registering DLLs. An uninstall log file would help also. You might have to boot from recovery media to get to it but it should be there if you log the uninstall.
You should treat this as an emergency before many more clients are impacted. Investigate root cause and issue a patch so that customers can safely uninstall.
The only thing I can see obviously wrong is that you think you are changing the Silverlight registry entries in the native 64 bit registry and the 32 bit Wow registry. Your install is x86 and you can't do that. If you're going to alter that key in the 32 bit world you just use the normal registry path and an x86 install maps it to WoW6432. So you have got two different components uninstalling the same thing, one of them incorrectly addressing the WoW6432 location directly. I don't know if this could screw things up but it's plainly wrong. You need an x64 setup for x64 systems, and as a matter of customer security I would not change those policy settings without making it clear to the customer.
The only other odd thing is that you seem to be installing the uninstall.bat file twice. What's in it? If it uninstalls the app, what's wronmg with using Control Panel? And hopefully that's not got anything that might be responsibe, if users are running that to do the uninstall.

The app I work on is written mainly in VB6.
Some users report that when they start up my app a different MSI installer will automatically run and try to repair its own installation. Often this is for AutoCAD but sometimes other programs also.
Usually this occurs every time they start the app.
What is a procedure that we can use to diagnose why this occurs? Since it is a third-party's installer which is running we don't have any visibility into what it is doing.
AutoDesk does have some info published on this:
Unexpected installer launches
Windows Installer displayed unexpectedly
but these do not directly provide enough information. Ideally I want to be able to completely prevent this from occurring to my end users, rather than just telling them how to avoid it or clean it up.
Your installer is acting on a directory, file or registry key that Windows Installer knows is part of the AutoCad installation.
First, I would turn on global Windows Installer logging. This means that any Windows Installer activity - including AutoCad's installer - is written to an external log file (in %temp%).
How to Enable Windows Installer Logging
Next, run your installer, and let the AutoCad installer run.
Now go to %temp% and you should find files MSIXXXX.LOG - one for your installer, one for AutoCad. Open these and you can work your way through them and identify which file or registry key the AutoCad MSI find is missing or changed.
You may find WiLogUtl.exe helpful for this:
Wilogutl.exe
With any luck you will identify that the directory, file or registry key triggering autorepair is also in your installer. If you're really in luck you can identify it as an item you should not be installing anyway - perhaps you are referencing a system component that would be present anyway, something protected by Windows File Protection.
If not, you will have to look at something like RegFree COM to move files out of shared directories into your private directory and reduce registry conflicts. Also, if you are using (consuming) the Visual C++ Runtime MSMs to make your MSI, consider using the Microsoft EXE installer instead or (best of all) placing the DLLs directly in your program folder, since I've found that the MSMs can cause just this sort of problem.
With regards to Peter Cooper Jr's comment on VB6 causing self-repair. Please check out the heat.exe documentation for Wix. You will see that there is a special switch the tool supports to suppress extracting certain registry values that are owned by the VB6 runtime itself (and hence shouldn't be messed with or updated by any other MSI): http://wixtoolset.org/documentation/manual/v3/overview/heat.html
Go down the list to the switch -svb6 and read the description to the right. (Reproduced here:)
When registering a COM component created in VB6 it adds registry
entries that are part of the VB6 runtime component:
CLSID{D5DE8D20-5BB8-11D1-A1E3-00A0C90F2731}
Typelib{EA544A21-C82D-11D1-A3E4-00A0C90AEA82}
Typelib{000204EF-0000-0000-C000-000000000046}
[as well as] Any Interfaces that reference these two type libraries
Does your installer write to these keys? If so try to exclude them - this is good to do even if it isn't the culprit in this particular case.
Other than that there is a lengthy description of what can cause Windows Installer self-repair here: How can I determine what causes repeated Windows Installer self-repair?. It is a long article because there are so many different ways self-repair can occur. The common denominator is that different installers on your system are fighting over a shared setting that they keep updating with their own values on each application launch in an endless loop.
I am having trouble uninstalling a package from Windows 7 that I myself have created with InstallShield.
Running remove program from control panel only got 1/2 way before it aborted and rolled back.
Funnily it reported the problem being one of my install steps, not one of the uninstall steps.
Frustrated I used the Windows Install Cleanup and the package is no longer listed under Remove programs.
However when I try to run the installer once more it reports that a previous version of the software must be uninstalled before it can proceed.
I was guessing that the Unique ID was still present in the registry but is not.
How exactly does windows determine that a previous version of the software is installed on my machine?
The best solution to an uninstall issue that prevents the product from being uninstalled is to debug the issue (often a custom action) and fix it or delete it, then rebuild the MSI with the same ProductCode. Then reinstall it with a command line:
msiexec /I [path to msi file] REINSTALL=ALL REINSTALLMODE=vomus
which updates the product in place and the re-cached fixed product will now uninstall. Otherwise (because you can't recreate the MSI) it is possible to go into the cached MSI in C:\Windows\installer and change the MSI manually with Orca, conditioning CAs not to run, for example. But you need to know what you're doing.
In other words and unfortunately, it would have been better to get the uninstall issue dealt with before resorting to the installer clean up utility, which I believe may no longer be supported because it doesn't completely clean up the system.
Your best approach now is to change your ProductCode, UpgradeCode and PackageCode because they'll be among the items on the system that Windows will use to see that your product is already installed. This stuff is in the registry, but it's obfuscated (rearranged guids) and scattered around.
I'm trying to use this Visual Studio extension for 2013, which recreates the built-in installer functionality from Visual Studio 2008/2010: http://blogs.msdn.com/b/visualstudio/archive/2014/04/17/visual-studio-installer-projects-extension.aspx?CommentPosted=true&PageIndex=2#comments
It works, allowing me to edit the project as before. It has the install and uninstall commands when right-clicking the install project, too. It installs fine.
When I try to uninstall, though, I get the following error and then the uninstall rolls back:
Could not open key: HKEY_LOCAL_MACHINE32\SOFTWARE\Wow6432Node\Microsoft\
EAPSIMMethods\18\FastReauthContext. Verify that you have sufficient
access to that key, or contact your support personnel.
I am not doing anything with that registry key, and there don't seem to be any relevant results on google-- at least not in the normal top 5 pages. Does anyone know what causes this or how I can fix it?
While I am not able to uninstall, I am able to increment the version of the package and allow it to remove the previous install and install the new version (all at once) successfully.
I am using Windows 8.1 Pro 64 bit, the projects are compiled for <AnyCPU>, and the installer is configured for x86.
EDIT I am running Visual Studio as Admin. When uninstalling from the Control Panel, I am also clicking the 'allow' button in the UAC dialog window that pops up.
I know how to give myself access to a registry key (permissions). I want to know why this key is trying to be removed. I support this app on several machines and I don't want to have worry about remembering an uninstall hack in the future.
EDIT This only seems to be an issue for a 32x installer on a 64x OS or a Windows 8 issue. I was able to use the same 32x installer to successfully uninstall the app on a 32x Windows 7 machine.
This must be an environmental problem, that key doesn't have anything to do with installers. EAP-SIM is an authentication protocol for wireless networks. The FastReauthContext key almost surely was meant to avoid having to provide a username+password each time your machine reconnects to the network. Which makes the registry key content very sensitive of course, it can only be read by a service that runs with the System account.
So, something goofy going on with your networking setup. Verify that you can successfully reconnect to such a network. If you used a VPN before then make sure it is active again. Something like this. Update your question with anything that might be relevant to networking when you first installed the app.
I have had similar problem and what I found out this is caused by MSI attempting to delete whole "Software\Microsoft" section in the registry. Lucky you that it encounters this error and rolls everything back.
So the solution is the following:
Since you have installed your program whenever you try to uninstall it the system will run msi from cache that is usually located C:\Windows\Installer.
Find your package in the cache. Here is an article that may help you http://csi-windows.com/blog/all/27-csi-news-general/334-identifying-cached-msi-packages-in-cwindowsinstaller-without-opening-them
Open the package in Orca. You must do this as administrator.
Go to Registry table and find record with "Software\Microsoft" as a key. Most likely the Name column will contain either "-" or "*" value. This means that during uninstall MSI will try to delete whole "Software\Microsoft".
Either change the Name value to empty or "+" or try to change key to something like "Microsoft". The second option will cause that installer will not find the key to delete during uninstall, but it will skip this error and let you uninstall your program.
You installed an untested installer on your dev machine? Speaking from experience, don't do that! Snapshotted VM's are cheap and will save you from this sort of pain.
Visual Studio Deployment Projects (or VSI as it's now called ) is known for creating very poor quality installs. The combination of those two put you where you are today.
I would need to look at the full uninstall log and your MSI using ORCA to understand exactly what is going on. MSI Zap and a manual cleanup of resources is probably required at this point.
it starts up windows installer with random applications on my machine . . after i click cancel a few times, it loads vb6 fine.
any ideas why this is happening?
To stop this behavior:
Start VB6
Open the Add-Ins dialog
Uncheck the "Visual Component Manager" Add-In

This is what a Windows Installer repair looks like. It means that something is broken in one of the installed products on your system. Ideally it's a one-off repair so you might be better off letting it runs its course and do the repair, except of course if it asks for a install CD that you don't have.
The Windows event log (Application) will have MsiInstaller entries saying what product and component has the problem.
It's possible a previous installation has not completed correctly.
Use the utility at the following link to remove any rogue installations files:
http://support.microsoft.com/kb/290301 (broken link Aug.2017, leaving URL for "historical purposes").
As PhilDW has pointed out this is a Windows Installer Self-Repair issue, and can often be resolved by allowing the self-repair to complete once. At other times the problem persists and it should be fixed by other means. Even when the self-repair completes and the problem goes away, it can still resurface once you launch the conflicting application. Windows Installer is not easy to deal with.
In your particular case you might be able to get away with a "workaround" rather than a fix. By locating the main VB6 EXE file on disk (in its main installation directory) and manually creating a shortcut to it on your desktop, you might be able to successfully launch VB6 via this new shortcut without the self-repair kicking in. It might be worth a try.
This shortcut trick will not remove the underlying problem, but might help to "bypass it". Just for the record: the reason this might work is that the new, manually created shortcut is not "advertised" and will not trigger a key-path check of the installed product when launched. This is Windows Installer's way to verify that a product is correctly installed. Note that even if the workaround works, self-repair might still result during application use because of faulty COM data being detected (which is very likely the cause of the whole problem you are seeing, but give the manually created shortcut a try).
There is a rather comprehensive "article" on self-repair here: How can I determine what causes repeated Windows Installer self-repair? which might help to track down the cause of the self-repair kicking off in the first place, but fixing it can be a rather complicated process (so try the workaround first). It is a long article because there are so many different ways self-repair can occur. The common denominator is that different installers on your system are fighting over a shared setting that they keep updating with their own values on each application launch in an endless loop. The last application to launch will overwrite the registry or file system with its own setting.
This worked for me, for VS2010 RC:
"Please wait while windows configures Microsoft Visual studio 2010 Ultimate."
THe work around that fixes the issue for me was to run the following via the admin cmd prompt.
Md "%ProgramFiles(x86)%\Microsoft Visual Studio 10.0\common7\IDE\FromGAC"
from http://social.msdn.microsoft.com/Forums/en-SG/vsprereleaseannouncements/thread/572a0f8a-16b0-4e1d-b581-16be36a9b564
This was also happned to me.
Whenever i tried to open vb6, it started windows installer to configure "Autocad".
Autocad had not broken. and it was working fine.
I tried removing and reinstalling Windows Installer, But it did not solved the issue.
Then i installed Microsoft's "Windows Installer Clean Up Utility 2" from given link.
Using this utility i removed the autocad from "Windows Installers" Database.
After that VB6 never started installer again.
Keep in mind 'removing any entry from installer's database may be risky, but i had no choice. So do it on your own risk.
Download "Windows Installer Clean Up Utility 2" (this is a deprecated, unsupported and unsafe tool to use - Aug.2017. I will leave the link in for "historical purposes", don't use it).
As most of you probably noticed, when uninstalling an MSI package Windows will ask for the original .msi file. Why is that?
I can only see disadvantages to that:
not resilient to network changes.
not resilient to local disk changes.
unexpected by users.
typically requires users to leave their desk and start a crusade to get the correct CD.
kind of proves installations are not self-contained.
promotes the use of unsafe tools such as msizap.
which in turn promotes the "next time I'll just use a zip file" mentality.
Could someone shed some light on this?
Fix Broken Uninstall: You can try the newest FixIt Uninstall tool from Microsoft if you have problems uninstalling an MSI. And one more link: Uninstalling an MSI file from the command line without using msiexec (a plethora of different ways to uninstall an MSI).
UPDATE:
This new support tool (this tool is now also deprecated) can be tried on recent Windows versions if you have defunct MSI packages needing uninstall (rather than the outdated, deprecated, unsupported msizap.exe).
Some have suggested to use the tool linked to here by saschabeaumont: Uninstall without an MSI file. If you try it and it works, please be sure to let us know. Feedback in that answer indicates that it works (I don't have any stuck setups to test with as of now).
Why are you asked for the original installation media?:
The original MSI is not needed for uninstall unless the MSI itself is badly designed - or the cached MSI is missing (see details below).
All installed MSI files are cached in %SystemRoot%\Installer\*.* using a random hex name.
The cached MSI file is used for any maintenance, repair and uninstall operations - and it is sufficient for uninstall in the vast majority of cases.
In some cases this cached file can be missing, and then uninstall is not possible at all in some cases (some theories as to why this can happen - MSI design errors, anti-virus quarantining, system restore, tinkering, developer system in erroneous state from development work, etc...). See more info below - and links to force uninstall or unregistration of the product.
The original source is only needed if files need to be copied to disk (for a maintenance install), or the MSI does an explicit request to resolve the original source via the standard action ResolveSource or via a custom action (which shouldn't be done in a properly authored package - I think the MS Office package contained this ResolveSource error back in the day, causing everyone to go looking for their installation CDs/DVDs).
In previous editions of Windows this cached MSI was stripped of all cabs, and hence contained the installer structure only, and no files.
Starting with Windows 7 (MSI version 5) the MSI files are now cached full size to avoid breaking the file signature which affects the UAC prompt on setup launch (a known Vista problem). This may cause a tremendous increase in disk space consumption (several gigabytes for some systems). Check this article and especially the discussion at the bottom for more intel.
To prevent caching a huge MSI file, you can run an admin-install of the package before installing. This is how a company with proper deployment in a managed network would do things, and it will strip out the cab files and make a network install point with a small MSI file and files besides it. Note that this may yield a UAC prompt is some cases since the extracted MSI file is no longer signed - this must be tested with your SOE / desktop configuration.
Read my answer in this thread for the full description of admin installs: What is the purpose of administrative installation initiated using msiexec /a? or this similar but perhaps more accessible answer: admin install and its uses
In some rare cases the cached MSI (with the random name) can be erroneously missing, and uninstall will then ask for the original MSI in order to complete the uninstall. This does not happen often. It used to be the case that one could use MsiZap.exe to clean out such an install, but this tool is outdated, deprecated and unsupported. Don't use it - there are too many incompatibilities with newer Windows versions and you create new problems. Perhaps try this support tool instead (also deprecated). The only option I can suggest now is this answer from saschabeaumont. If you try this tool, please let us know if it works for you. If you want to figure out what could have caused the cached MSI to be missing, try to read section 12 here: Uninstalling an MSI file from the command line without using msiexec (in short potential causes range from interference with system restore, anti virus and cleanup scripts, to erronous manual tweaking, low disk space, power outages, developer box debugging errors, badly designed MSI files with duplicate package codes, failed patches, etc... Many theories, few certainties I am afraid).
As a last resort you can try system restore (unless it has been disabled entirely or partly) to go back to a previous installation state and see if this solves your uninstall problem (you can find video demos of this on youtube or a similar site).
Be aware that system restore might affect Windows Update that must then be re-applied - as well as many other system settings. I have seen new, unsolvable installation problems resulting from a system restore, but normally it works OK. Obviously don't use the feature for fun, it's a last resort and is best used for rollback of new drivers or setups that have just been installed and are found to cause immediate problems and such issues. The longer you go back the more rework you will create for yourself. A lot of self-evident stuff, but I guess it needs to be mentioned.
Since I mentioned system restore I suppose I should mention the Last Known Good Configuration feature. This feature has nothing to do with uninstall or system restore, but is the last boot configuration that worked or resulted in a running system. It can be used to get your system running again if it bluescreens or halts during booting. This often happens after driver installs. This will do nothing to fix your failing uninstall though (or I would be very surprised).
Related answer:
Uninstall without an MSI file
In addition to this answer, perhaps this article on various ways of uninstalling MSI packages is of interest. It is a rather popular article with a high number of views:
Uninstalling an MSI file from the command line without using msiexec.
There are a few reasons for keeping the original msi:
The uninstaller uses it to know what files and registry keys were installed and make sure they are all cleaned up.
The msi may contain special uninstall actions that need to be performed.
It allows you do to a 'repair' operation from the Add/Remove Programs menu, regardless of whether or not you saved the install file yourself.
The normal way of things is for Windows to keep the file cached for you, so you don't have to think about it. See your %WINDIR%\Installer\ folder. The only reason it would ask your for the original msi is if something is wrong with the saved file. This addresses most of your concerns, though it does raise a new one (disk-space).
