Windows Installer - force users to remove via Add?remove Programs - visual-studio-2005

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.

Why app installed using MSI installer would disappear from Windows

We made some changes to the installation and updating process of our Windows app recently, and some users are now complaining that Windows sometimes automatically deletes the main application .exe file.
It usually occurs after users update app using built-in web update feature. The feature is implemented using .msi built in Advanced Installer tool.
We are struggling to figure out what is causing this, and haven't found a way to consistently reproduce the issue (though we've seen it happen as well).
Here's what changed with our installation and web updating process:
The main installer for our application is now a standard .msi, which becomes a part of the Windows installation system and is natively manageable by Group Policy and other system features, such as rollback or versions. In previous versions that did not have this problem, our installer was a .exe built with the SetupBuilder tool.
We introduced the redesigned web updater feature inside the app (to update to new versions within the app). It uses the same .msi as the main deliverable as for installation. .msi is downloaded from our server in a form of .exe which is then extracts MSI and starts it. MSI then updates file in our installation. These .exe and .msi is built with Advanced Installer tool which provides such a web update feature to developers. In previous versions that did not have this problem, our web update feature was developed with SetupBuilder tool which provided a custom web update files - .exe web updater that downloads a number of web update files containing patch to our app.
The goal of a transition to the standard .msi installer was to make it easy for our clients to deploy the app in organizations - say, mass deploy using group policies and other similar tools.
Has anyone else experienced a problem like this? Any ideas on how to troubleshoot and try to reproduce?
Theory: Before doing anything else: The first thing I would ask the people who report the problem is if they have re-packaged your older, legacy (non-MSI) setup to be their own MSI file? This can cause a well-known upgrade problem along the lines of what you explain (file missing). Please check first. Tell them to uninstall the existing version and then install the new one - that is the simplest way. Not always enough (some obscure problems possible).
Mismatched component GUIDs could cause missing files after upgrade, as could file version downgrade scenarios and various other technicalities. You could try to install to a new default location on disk to avoid these problems. The reason this can work is very technical and hard to explain tersely. Essentially you de-couple yourself from "the sins of the past". It is generally enough to change the name of the file in question: for example MyApp.exe to MyAppNew.exe or maybe add the major version: MyApp5.exe, but maybe try the folder change first ProgramFiles\MyCompany\MyApp => ProgramFiles\MyCompany\MyApp5.
How do you configure your upgrade? View "Upgrades", what is selected: "Uninstall old version first and then install new version" or "Install new version first and then uninstall old version".
Blog Entry:: Why Windows Installer removes files during a major upgrade if they go backwards in version numbers (might be of help).
Deployment Debugging: For open ended debugging of MSI and deployment problems in general one obviously needs to gather intel and that means logging and system inspection.
Logging: First try to get a proper log file for the systems where this problem occurs. In Advanced Installer you can tick the "Enable verbose logging" in the Install Parameters view to enable verbose logging for all package installations. This adds the MsiLogging property to the compiled MSI and every installation of the MSI will cause a MSI log file with a random name to be created in the TMP folder. View the folder, sort by date and the file should be at the top. Suggest you do this and then tell the users to send you the log files when relevant. Maybe you have this setting enabled already?
Further Logging: There are many ways to enable logging, and you can find a description here: Enable installation logs for MSI installer without any command line arguments. The MsiLogging property is just one possibility.
To log a single MSI setup: http://www.installsite.org/pages/en/msifaq/a/1022.htm.
To enable global logging for all MSI operations on the machine: Please see this FAQ-entry from installsite.org, section "Globally for all setups on a machine" - for the exact procedure.

Installshield : custom action to uninstall previous version and install the latest version

My requirements are as follows:
If an application with version e.g. 12.0 is installed at C:\Folder1 and a setup with version 13.0 is to be installed in the folder C:\Folder1 then the setup of version 13.0 should uninstall 12.0 version silently and install the latest version 13.0
If an application with version e.g. 12.0 is installed at C:\Folder1 and a setup with version 13.0 is to be installed in the folder C:\Folder200 then the setup of version 13.0 should install the latest version and also retain the version 12.0
Things I have tried :
If I use the upgrade code method to uninstall the previous version then the uninstall of previous versions will happen even if the previous version is installed anywhere on the system.
Using custom action - create a vbscript to read the installed products using WindowsInstaller.Products data and using the Product code created a command to uninstall the application using "msiexec.exe /x ProductCode"
This custom action when added in the "Before File Transfer" section in install shield project, gives a pop-up that "The application is installing the version and to wait till it has completed the process".
The "Wait for Action" property for the custom action is set to Yes.
I tried setting it to "No" as well still same pop-up appears.
If I add the custom action in the section of "After setup complete Success Dialog" in install shield project, then both versions are installed and after the vbscript executes, it does uninstall the previous version.
The problem with this approach is, when I double click on the desktop icon of the application; it starts installing and displays pop-up of the progress of installation. This would be confusing for the customer.
So this approach is not suitable.
We have not added any data in registry so cannot use the registry method to uninstall previous versions.
This is a very basic requirement for any software, but I am not able to make out how to achieve this. Please let me know if anybody has some pointers.
I have Installshield limited edition 2015 and Visual Studio 2015 Professional.
This actually is not a "basic requirement for any software." The basics are if a ProductCode/UpgradeCode is installed upgrade it.
For point 2 you're getting the pop-up because you're trying to run 2 MSI ExecuteSequences at the same time. If you'd like to continue down this road you'll have to move your uninstall action to the UISequence. Beware that silent installs will not run this action since it never hits the UISequence. Also, the better way to head down this road is to build your own bootstrapper (setup.exe) that controls the flow of uninstall/install.
You can't do that because an upgrade (a major upgrade) MSI doesn't care where the previous version of the product is installed. An new MSI with an UpgradeCode (and a few other details) will upgrade an existing product that matches, uninstalling that older product wherever it's installed.
Some Issues (not a complete list):
If you want to install another product and NOT upgrade the existing product then you need an MSI that (for example) has a different UpgradeCode or doesn't do a RemoveExistingProducts.
Your MSIs (old and new) need to set ARPINSTALLLOCATION, so you can ask where they are installed. That lets you compare install locations (but IMO not an ideal solution).
There are issues such as whether the two separate installed products now have the same shortcuts in the start menu, whether there are any shared files in common locations, whether there are any non-shareable items (service names, global event names etc).
There are also maintainability issues, such as how to upgrade or patch two almost identical installed products.
Anyway, I would simply ask the user if they want to an upgrade or a side-by-side install, rather than base that decision on a choice of folder (which seems IMO an unusual side effect of choosing an install location).
The general choices are probably based on having a condition on the RemoveExistingProducts action, based on a command line property or other mechanism. Or, depending on maintainability requirements you could change the upgradecode (with a transform on the command line) so that the upgrade doesn't occur. It's not clear to me that detecting the install location of the previous MSI in the browse folder dialog of the new install is straightforward.
I am afraid MSI does not lend itself too well to this sort of scenario - as you have discovered.
Is this a corporate software, or is it for general, large-scale distribution?
What is the purpose of this multi-instancse approach? Does this MSI effectively install two different versions of the same application?
Instance Transforms: I suppose you could investigate the instance transforms concept. It is intended to allow multiple installations, but I dislike the concept and have never used it actively. I am hence not able to give you the inside story of limitations and gotchas - sorry - maybe someone else can illuminate?
As PhilDW states you can use another upgrade code for the newest MSI, and then install side-by-side with the old installation. Beyond what has already been mentioned you would also need to change all component GUIDs for the new package. WiX allows component GUIDs to be auto-generated based on destination path, but not so for Installshield. The instance transform should be possible to use to install side-by-side without changing all component GUIDs - I believe.
App-V: If you are in a corporate setting, and if I had enough experience, I would also recommend that you check out App-V packaging (virtualization). This allows isolation of applications so multiple versions can run side-by-side. But again, I am not the right guy to give you the inside story. I know there are a number of limitations, but can't elaborate with real-world experience.
Setup.exe Launcher: If your application gracefully handles multiple instances without clashing shortcuts and service name etc... (like Phil describes), then you could install all new versions side-by-side and never uninstall older versions by default via the upgrade table. You could then handle the uninstall of previous versions manually in your setup.exe launcher (if any). I suppose you could use the instance transform concept to install new versions, or you could re-create your setup for each new version with all new component GUIDs and product, package and upgrade GUIDs.
Legacy Installscript Project: I suppose you could abandon MSI and use a legacy Installscript project to deploy your application. I would not recommend this since such projects are problematic for reliable remote management and silent running (both for install and uninstall).

Multiple entries in Add/Remove Programs of my application

I am using Visual Studio 2013 installer to package my application. I then make a copy of the MSI, open it in Orca and remove all the dialogs to create a silent package. So I have two MSI's that should be the same other than one is silent and the other is not.
When I upgrade from a previous version (built in the same way) using the non-silent package, everything works perfectly.
However when I upgrade from a previous version using the silent package, it all works apart from I am left with 2 entries in Add/Remove programs. It all works though but looks ugly for the client. When i uninstall the latest version, Add remove programs still has the previous version listed in Add/Remove programs although actually the latest version is still installed.
As I say, the non-silent package works perfectly well, which leads me to think I must have everything setup correctly in Visual Studio and Orca must be doing something I didn't intend.
Any help would be much appreciated.
If you have two entries in Add/Remove Programs then the upgrade didn't work. A common reason is that one of the installs is Everyone and the other is Just me. If you delete the dialogs then you have altered the behavior that sets the ALLUSERS property, and your upgrade could default to Just me. In the absence of a decision to use one of these choices VS setups use ALLUSERS=2 which is defaulting to a per user Just me install, that's the likely reason. Elevation is involved too - VS setups would rather your MSI did a successful Just me instead of a failing Everyone if privilege state is not clear (and in MSI setups it often isn't).
You might need to go to the Property table and set FolderForm_AllUsers to "ALL" and ALLUSERS to 1 to force a per machine Everyone install.
How silent do you want it to be? If it requires elevation to install successfully then you need the elevation dialog to be shown or the install will fail silently if you force a per machine Everyone install.

how to get the name of the feature being installed using wix managed bootstrapper ui

I am using WiX to install a executable and I have used ManagedBootstrapperApplicationHost for CustomUI.
Is it possible to get the name of the feature being installed at the time of installation ?
If possible then how can we get the name of the feature ?
Any help would be appreciated.
Thanks.
Features aren't installed one after another. For example if 3 features are being installed, each with 10 files then the InstallFiles action will install all 30 files at the same time. Same thing with registry entries. So you can't display a UI that says "Installing Feature1" and then later on "Installing Feature2" because that doesn't happen. All you can know is that some list of features are being installed.
Your comment asks about finding out whether a feature installed successfully or not. This issue never comes up - there are never some features that install and others that fail. An MSI install is a transaction and it either all works or fails and rolls back and deletes changes it made so that the system is restored to its previous state.
It's not clear why the list of features is so important to display. If you use the MSI's internal UI there is a feature selection dialog where the user selects which features are to be installed; if you use the Burn UI the same thing is available, so the user can see what features have been chosen.
Inside the MSI the list of features being installed (after they've been selected) is in the ADDLOCAL property, but that's the internal name. It could be used to display a list of the features that were installed at the end, but again by definition what was chosen is installed otherwise the install would have rolled back entirely. I don't believe I've ever seen an install where the list of MSI features installed is displayed at the end - it's redundant info. It would be useful to know the scenario you have, or what problem you're trying to solve, and if you believe that you need to display a list because some might install and others might fail then there is no point, as I have said.

Can't get MSI minor upgrade to work

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.
