A user aborted a IS6.31 install near the end of the install, then attempted to "manually" uninstall our app.  He did a search on the app name, then deleted all registry keys containing that name.  App doesn't appear under "Add/Remove", and he deleted the entire program folder and all subfolders/files.  When he tries to run the setup again from a CD, he is asked if he wants to uninstall.  If he says yes, the uninstall "completes" in an instant (doesn't do anything).  Is there a way to "force" an install, or does anyone have suggestions on how to complete the uninstall manually?  Thanks in advance....

Missed one.  The user will also need to delete the following files:
x:\Program Files\InstallShield Installation Information\<Install Product GUID>

Once that's done, it should go through just fine.

As for forcing it, there really isn't a way to do it for an install that's already been distributed.  For future ones though you can either take the extreme approach and drop the whole IS6 event model and its correponding maintenance mode idea, or simply add command line switches to try and override this behavior when necessary.

Thanks for the quick response.  User claims that x:\Program Files\InstallShield Installation Information folder does not exist.  Any ideas what else could be causing this?  User claims that all registry entries containing our AppName have been deleted... Thanks!

Humm, well in that case try having the user delete any references to the <Install Product GUID> from the registry.

IMO it would be sufficient to delete

HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\$PRODUCT_GUID

Best regards,

Thanks, that did the trick!

Yeap, that's the main one I was referring to in the registry.
