derekf's blog On C#, repackaging applications, and deploying via group policy...

Even though I'm no longer involved with group policy, I'm still the go-to guy for issues.

Got a call this morning from a helpdesk guy who was working an issue with Add New Programs not populating.  He'd dug through RSOP and found that two apps had failed to remove. (More specifically, RSOP showed the yellow bang on User Configuration/Software Settings/Software installation, with these two listed as "Removed Applications").  The details for these two apps specified "The removal of xxx from policy yyy failed.  The error was : The installation source for this product is not available.  Verify that the source exists and that you can access it"

A little digging found that both of these apps had been removed from policy with the "Immediately Uninstall" option months ago, and somewhere along the way the app folder was removed from the local servers.  One of the apps had the folder contents available; simply replacing it on the local server was sufficient to allow the uninstall to complete.

For the other app, the source no longer exists.  Most users were able to uninstall with the local cached copy, but this user no longer had that MSI.  Helpdesk will be using MSIZAP to get rid of the registry entries for this app so the user can install the newer revision of this app.

Not sure how long the user has been having trouble.  The lesson to be learned here is to not be in such a hurry to remove the source from the local servers; users may need it for a while after if you've removed it from policy with "Immediately Uninstall", or if you're going to ever push out an app as an upgrade to this one.
