I'm currently working with InstallShield to deploy a .NET Winforms app. I am new to InstallShield and have not enjoyed the learning curve. The Winforms app has three related DLL's which are not getting updated during a minor upgrade. For a minor upgrade I am changing the version from 1.0.001 to 1.0.002 for example. The package code is being changed for each build automatically.
I have tried adding the dll's to the [INSTALLDIR] and setting the property to "always overwrite". For some reason this causes the upgrade to also not update the main exe.
Tried changing the product code to force a major upgrade. This installed a new version alongside the old version, but the new version still had the old dll's.
Tried changing ReinstallMode from "omus" to "vomus". This had no effect at all.
Tried using REINSTALL=ALL, REINSTALLMODE=vomus. This did not update the dll's and also caused new installs to fail with message that application "is not marked for installation".
Tried changing the version from 1.0.00x to 1.1.00x. dll's still not updated.
I notice that when I view properties of these dll files, they have File Version = 1.0.0.0 and Product Version 1.0.0.0. Do I need to manually increase these versions in order for InstallShield to recognize that they have been updated?
Use one component per file and set each file to be keyfile in its own component. This avoid all sorts of component referencing and file replacement issues. Be aware that multi-file assemblies must share the same component as they are intended as one "atomic" file system unit.
In addition you must also increment the version number for each build or set REINSTALLMODE to emus instead of the default omus. Never use amus.
My advice: go with the file version updates - it is much more reliable. Like you state the File Version is used, it must be incremented. I like to auto increment the build version number (last digit). It has been a while, but I think you just replace the number with * and it auto increments. I think you can do this from the Visual Studio project property view.
Maybe read up on the file versioning rules as well. Essentially versioned files are version compared, and for unversioned files the create and modify date stamps are compared and the file is replaced if it is unchanged on disk. More sample info.
Remove the "always overwrite" flag you enabled for all the files you enabled it for. This flag may work poorly with patches if you ever need them and also with other features.
When a major upgrade creates two side-by-side installations it hasn't worked. What you are left with are two different products installed at the same time. There is good inline help in Installshield itself with regards to how a major upgrade is set up. Which version of Installshield are you using? The version bundled with Visual Studio may not feature this help material.
A note on major upgrades and "reverted files":
A warning on a classic major upgrade issue: be aware that changed, unversioned files not set to be permanent on original install may be uninstalled during a major upgrade and then reinstalled yielding the impression that they have been replaced, but they are actually deleted and recreated. These are typically important settings files like XML files or similar - and people struggle with this issue a lot. Major upgrades are essentially a sequence. The old product is uninstalled, and then the new one is installed or vice versa. In the former case the files may be uninstalled first and then recreated. This does not happen in the latter case if component referencing is done right because the files that are matching between products are not uninstalled, but retained and then overwritten if need be (according to the file replacement / versioning rules).

I have a Visual Studio 2010 Setup Project and I am trying to create an Upgrade to a new version of my software.
The upgrade process is running. I properly updated the Version Number, which caused an update of the Product Code. RemovePreviousVersions is also True.
My problem is that when I upgrade my software, there is one file that may have changed on the local filesystem, in the course of running the software. I'm finding that, because the file changed, the installer refuses to overwrite it.
I want my installer to force this file to be overwritten with the new version.
Is there something I can do -- within Visual Studio, with Orca, or otherwise -- to force a file to be overwritten even if it has changed?
UPDATE: In Orca, I noticed that the "File" table includes a "FileSize" column. I believe this might be the reason the file is being ignored. If the size of the file has changed, it doesn't match. Is there any way to override this?
You can't safely change the Windows Installer replace rules, but you are getting into this situation because the upgrade mechanism first installs the upgrade on top of the older product (invoking file replacement rules) then uninstalls the old product, ref counting down and removing the product. It's the "on top" that is the issue. If you move RemoveExistingProducts in the InstallExecuteSequence from just before InstallFinalize to just after InstallInitialize you will get a complete uninstall of the older product then the install of the new upgrade. That may not work if you are expecting to keep data files around.
Otherwise you could use the RemoveFile table with Orca. You'd add an entry targeting the Component name corresponding to the file (look in the File table, and there may already be some entries in the RemoveFile table as examples). You'd set the value to be Remove on Install. The RemoveFiles action occurs before the new files are installed, so it should work.
I have a question concerning software updates. Currently I install new releases into a different folder each time. The user is then required to re-enter configuration parameters. This of course is not too optimal. The software is Windows forms and I use the settings. Settings file.
So the question is what happens if I install a newer version into the same folder as a previous install? Will files just get replaced? What about if I have added settings in the new version? Will they be merged?
Anything to watch out for?
Thanks
When the MSIs are related, typically you can only have one instance of it installed at a time. If that's the case, first the earlier version may be uninstalled, so the question is whether the files that store the settings are removed by uninstalling your MSI.
If the MSIs are not related, you can get into a world of pain by overlapping their installations (probably breaking component rules by having two different components describe the same file in the same location, but with a different component code), yet the core question comes down to the same thing: will the updated installation lay down the file that stores the settings.
These are likely the same question, as the easiest way to remove or install a file is by including it in the MSI directly. (There are other ways, but I'm assuming you're not using those yet.) If the file is not part of the installation, nothing will happen to it, and the answer to your question comes down to what your application does when it runs with a settings file created in a different version. If the file is part of the installation, and component rules are not being broken, it will either be uninstalled then freshly installed (wiping any configuration), or per File Versioning Rules and Default File Versioning, the file will either be left untouched or completely replaced with the new version. Windows Installer doesn't know how to merge your settings file.
Thanks for taking the time to answer my question.
So bottom line I should just avoid these issues and install in another folder. I should also make a copy of the settings and put them in my own file which can be used to update my new installation. That would be the safest route I guess.
Thanks
I have an InstallShield InstallScript MSI project that contains the FLEXnet Connect without Software Manager merge module. The version of this product is 6.0.32. I created a second installer for version 6.1 that also contains the FLEXnet Connect without Software Manager merge module. When I perform a major upgrade on a system that contains the 6.0.32 version I get a message in the MSI log stating:
Disallowing installation of component: {FF970098-B748-427B-B946-AA8E1A1F82AD} since the same component with higher versioned keyfile exists
The component is referencing the isusweb.dll file located in the FLEXnet Connect folder.
It looks like this check occurs prior to the 6.0.32 product being removed. The install proceeds to remove the 6.0.32 product, which removes isusweb.dll. During the 6.1 install the isusweb.dll is not put back because of the component version check.
The upgrade succeeds. When I attempt to run the application from a shortcut it verifies the components. Since the isusweb.dll is missing the MSI attempts a repair, then cannot find the MSI and does not allow the application to open.
Is there some way to get the merge module to always overwrite?
This sounds suspiciously like this bug:
http://support.microsoft.com/kb/905238/en-us
and I've come across this bug and you do see that log message, and RemoveExistingProducts is early in the install. It decides to not install the file based on the higher version being there, but doesn't re-evaluate that decision after the REP removes it. Then a repair restores it when you use a shortcut. The bug should apply only to files in the GAC or SxS, so that's a bit puzzling.
If you can schedule REP at the end of the transaction sequence (InstallExecute, REP, InstallFinalize) that should fix it - might be worth a try, all other effects of the move being ok.
Merge modules don't get installed, they get merged. Product MSI's get installed. One of the problems with using third party merge modules is if they have a bug, there isn't much you can do about it.
I'd consider creating an MSI solely for the purpose of encapsulating this MSM. Then I'd create a setup prereq or suite installer to install this MSI apart from your product MSI.
You have got two really good answers already, but to try and synthesize:
It really sounds like a buggy merge module. Phil suggests to fix your REP placement in the InstallExecuteSequence to work around the bug. Chris suggests to put the faulty merge module in its own setup. I agree with both and think you should follow both suggestions:
Remove the merge module from your main setup.
Create a new setup and add the faulty merge module and ensure the right REP sequencing.
For the REP fix to work your component referencing must be 100% correct - now and in the future. To eliminate this as a problem creating a separate setup allows you to contain the buggy module inside its own MSI. This will help you avoid re-activating the bug by mistake or by changed design in the future - and the latter is never unlikely.
As Chris says: a merge module isn't delivered, it is merged. An updated merge module may be available for all I know, but even then it is wise to contain it. Especially when you are dealing with the GAC (Global Assembly Cache).
Another solution that I applied when encountered this bug was to set to update the "Version" column from File table, in the merge module, using Orca. Set that to the maximum 65535.65535.65535.65535, this will force the upgrade to always install the DLL from the merge module.
When I try and apply a minor upgrade to my application, I launch the installer and (depending upon the combination of settings I try) I get either a:
repair/remove dialog
prompt for the install directory
I don't believe I should get either of these prompts. I'm mostly expecting the installer to automatically apply the upgrade and not prompt for anything. I think I'm doing everything correctly in the Visual Studio setup project:
upgraded the version from 1.0.0 to 1.1.0
left the product code the same
updated the package code
left the upgrade code the same
launch the installer with the parameters REINSTALLMODE=vomus REINSTALL=ALL
I've tried just about every combination of codes/flags and techniques, but cannot seem to get the update applied.
Any ideas of what else I can try?
To get it to work I:
upgraded the version from 1.0.0 to 1.1.0
left the product code the same (said No when prompted by Visual Studio)
updated the package code (Visual Studio did this automatically)
did not change the upgrade code
launch the installer with the parameters REINSTALLMODE=vomus REINSTALL=ALL
Just as I had indicated in my question, and it seems to be working. I can successfully apply an upgrade. However, when I run the installer I am still prompted with a repair/remove option. But, that's a different question I guess.
Just first things first: Are you sure you haven't re-used the package GUID in both MSI files, or at some point during deployment work and testing?
Try rebuilding both MSI files with new GUIDs to "de-couple" them from any existing cached versions and then try test installing again. Change both the package code and product code. Better yet: test these new versions on a clean virtual machine to ensure a proper test environment unaffected by past sins. Your developer system could have gremlins in its Windows installer database due to package guid clashes. If this is the case package installation becomes total XFiles - the strangest things can happen.
More details:
If the package GUID is the same for two MSI files, Windows Installer will treat them as the same file by definition - no matter what they contain. This can cause all kinds of strange problems that are hard to clean up and debug. Note that this can happen even if you just forgot to update it once since installation of an MSI will cause it to be cached on the system in the C:\Windows\Installer folder (this folder is hidden and protected). This cached copy will be re-used if an MSI file with the same GUID is launched (at least this was the case for earlier versions of Windows Installer - there could be fixes for this now).
If you are using Installshield you should enable the "always generate packaging GUID" feature to ensure this never happens. Package GUID should always change for every single build - there is no reason whatsoever to keep it hard coded. I believe WIX takes care of generating the package GUID automagically, unless you specifically override it.
We have an installer solution written in Visual Studio 2005 Installer; that calls a C# custom action and we have hit a known issue, regarding the fact that on an upgrade - the old install code is run and not the new code, because Windows is running a cached version of the custom action dll. We know this and although not over the moon about it - we have moved on.
When we release a new version of the installer and a user runs it, we now want it to check to see if an ealier version is installed - if there is one; we want to display a message telling them that they have to remove the old version via Add/Remove Programs. We know if they do a manual uninstall followed by an install, then all is fine and dandy - BUT it doesn't matter how many times we tell our users, via documentation; that this is what they have to do - they will still try and just run the new installer, without removing the old version first.
Therefore, we would like to put up a message and thus force them to to what they are told !! I've seen some installers do this ( though of course not sure what installer package was used to create these ). We only have VS 2005 and of course orca !!
Cheers,
Chris.
This can be done through a custom launch condition:
create a search which determines if the old version is installed (you can search for a component, registry entry or file)
use the search property as a custom launch condition
For example, if the search property is OLD_VERSION, the launch condition can look like this:
Condition: NOT OLD_VERSION
Description: An older version was found. Please uninstall it using "Programs and Features" in Control Panel.
When OLD_VERSION property is set to a value (an older version is found), this launch condition will show the message and stop the install process.
This doesn't quite make sense. Have you remembered to change the package GUID in your new setup? The package GUID identifies a specific setup file, and if two MSI files have identical GUID they will be treated as the same file regardless of whether they are or not. This could trigger a cached version of the MSI to be invoked and all sorts of hell breaks loose.
I would recommend reading up on "major upgrades" which will allow automatic uninstall of the existing version before the new version is installed. You also need to make sure you understand the basics of the technology before deploying to the wild. You must NEVER use identical package GUIDs for any MSI files. It's practically always wrong, and will lead to very mysterious problems.
I can't write up the whole major upgrade solution here, but basically it involves authoring the "Upgrade" table of your MSI to detect versions to uninstall. You need to change the package code, product code and version number (only 3 digits matter) and keep the same upgrade code (two MSI files with the same upgrade code "know" they are related - i.e they are from the same product family). Check MSDN for samples of major upgrades.
NB! If you have deployed MSI files with duplicate package GUIDs to your developer machine, it could have stray installs that must be cleaned up with MSIZap or similar. Use caution, or better yet test your new installer on a clean test system. Developer systems are full of junk and not generally good for MSI testing.
