View Full Version : How does an uninstallable patch appear on system?

07-22-2005, 10:43 AM

A general question at this point. I have migrated my Dev. 8 InstallScript MSI projects to Dev. 11, everything is working fine now. We use patches heavily and I am investigating how to make the patches removable (i.e. v1.0.0 -> 1.0.1 -> 1.0.0). All systems running Win XP sp2, with windows installer 3.1 installed.

In my patch configuration, I have enabled the "Allow this patch to be uninstalled" option. I have read all the windows installer docs I can find and have attempted to set the systems group policies to allow rollback of patches, etc.

Well needless to say, while the patches are working, I cannot see that they are uninstallable. Nothing different shows up in add/remove programs.

What should I be seeing in XP that would tell me the patch can be uninstallable? I would expect some kind of subentry in add/remove programs under the main appl. name? Is there some build log file entry I can track to see if the 'uninstallable" aspect of the patch is working?
