I'm trying to uninstall a previous version of my application as a Custom action.
I use a VBscript stored in the custom action:
dim shell set shell=createobject("wscript.shell") shell.run " C:\WINDOWS\system32\msiexec.exe /x {43A14B97-7678-4809-8A19-843B2EBF9C3E} /quiet" set shell=nothing
When I perform the install, it looks like the msiexec.exe gets invoked, because the system32 windows appears, but the application does not get uninstalled.
Is there some way of doing this short of manually using the control panel Add or Remove programs?
You might look into creating a "major upgrade", which uninstalls any earlier version when the newer version is installed. The online help has more information, and the Upgrades view can help.
