I am creating a Basic msi project. During uninstallation i have to create specific registries in the system. So i created a Custom action(Immediate) and placed in between install execute and install finalize.
The installer works well in XP, but in Windows 2008, when i uninstall from the Shortcut the installation fails at the custom action which of interest.
What i noted is if i use Setup.exe to uninstall, it uninstalls perfectly If i uninstall throuhg ARP, it uninstalls perfectly. But when i uninstall through shortcut, it throws error saying registry cannot be created and rollbacks.
To elevate the setup.exe, we have the option to set Required execution level=Administrator in release wizard. But the uninstall shortcut refers to the MSIEXEC.exe. Is there any way to specify the required execution level for Msiexec.exe
I think this problem is due to the split tokens of Vista, but can your plz help me in setting the admin priviledge for launching Msiexec.exe?
The msiexec elevates itself during the uninstallation, but i think the custom action tries to change the registry before the elevation of msiexec.exe. So you need to change the sequence of your custom action. or a common work around for this issue is to right click the shortcut and select run as administrator.
I had similar symptoms to yours with my setup a while ago. It was related to the first item in the list above: I had forgotten to add one property to the SecureCustomProperties property.
