I've developed a Wix installer for an internal project however entirely by accident I've found that I'm unable to uninstall the installer on my development machine as I get the following error message:
The feature you are trying to use is on a network resource that is unavailable
with a dialog pointing to the path of the .msi that I installed from feature from. (The .msi is there, however is has been rebuilt and so has changed since I installed it)
I'm concerned by this dialog as I had believed that Windows Installer kept track of installed .MSI files, however this dialog seems to suggest that I can break my uninstaller by deleting, moving or changing the installer.
Is this the case?
What do I need to do to make sure that I don't break my uninstaller in this way? (Do we need to keep copies of all versions of the installer ever installed on a machine?)

The easiest way to get out of this situation is to do a recache/reinstall. Build a new version of your MSI that isn't "broken" (in whatever way it is broken, in this case, it might not really be broken at all, you just need a new source). Then you use a command line like:
That will copy your.msi over the MSI that is cached and do a repair. Then you'll be in a better place.
