[wix-users] Wix Bootstrapper Not Uninstalling Self Upgraded MSI

Thu Apr 16 10:25:22 PDT 2020

I would make it a light weight web based installer. Either you’re using burn and have all its goodness, or you’re doing something custom and you deal with the fallout.

Calling a bundle an ISO makes me wonder if it really is an ISO, if so you can easily do a web based install, then do a /layout and burn the layout to an ISO for the users to download.  Newer bundles can use the existing artifacts if they didn’t change.

The bundle (ISO file) includes many installers and prerequisites, some of which are not wix based and versioning can be a bit tricky. It is also multiple times larger in file size than the MSI installer/updater we would like to distribute. Our ideal scenario is to just distribute one of the MSI installers that will update the client app and related api’s and services only.

I’m still confused as to why the bundle can’t just be updated…

Yeah, hard problem. A perfect solution would open the door for us to implement a solution. If you find one, a great thing to discuss on wix-devs.

Hello Rob,

Great points. Something that I did not think about. It seems that custom actions are not available in the bootstrapper bundle anyways. I was going to use the ExePackage to run a batch file that will uninstall the separately updated MSI based on conditions but your first point in your reply stopped me in my tracks.

Again, think about what happens if during the uninstall, after this custom action executes, an error is encountered and the bundle has to rollback. How do you reinstall the package your custom action uninstalled?

Also, if your bundle is per-machine, consider what happens if a malicious MSI was installed per-user and your script decides to uninstall it elevated.

The lack of solutions to those problems (particularly the first one) are the reason there isn't a "more native" way to handle this today.

Hi All,

Thanks for the response, Matthew. That's the route I was heading but I wanted to make sure there were no cleaner (more native) way to handle this. This route would mean that I would add the custom action to the bundle with an uninstall condition to ensure the powershell script to uninstall the MSI is only run during a bundle uninstall. Is there any way to make the change to the MSI installer (also WiX project) directly and somehow keep that dependency link it has to its parent bundle when upgrading the MSI separately?

Hi All,

Just my tuppence worth, but I am by far an expert in these matters.

My understanding is that when a bundle is installed, all components are linked as dependencies in the installer catalogue on the machine.
When you upgrade a component separately, the new version doesn’t have that dependency link and so the bundle uninstall skips it.

I believe that is expected as if you were it install that component manually for another reason (maybe it is required for another app) then you would not want the bundle to uninstall it as then that would break the other apps that require it.

If you do want that ability because you are 100% sure you won’t break anything (e.g. you are in control of all deployments) then you could create a Custom Action instead that runs a PowerShell script to specifically uninstall that component regardless of version.
However, it is not advised to do this.

Regards,
Izzy

I would think the bundle would still be able to uninstall it when the bundle itself is uninstalled due to the MSI having the same upgradecode. Instead I am finding the MSI orphaned and left installed when uninstalling the bundle.
