MS Office Forum / General MS InfoPath Questions / October 2004sp1:BUG:MSI/Registry unistall/reinstall problem
I install a local Infopath trusted form using a msi file. I unistall it. Then when I try to reinstall a new version, I get the message that the form is already installed, pls unistall it. Its not on the Add/Remove programs list any longer. Trying to find a workaround, I noticed in the registry there is a "Recent Templates" key that has entries with the URN for the various forms that have been installed. I noticed that the urn for the form that I uninstalled is still there. When I delete that entry, the install works fine. It seems to me the uninstall needs to automatically delete that entry and that new installs of that form need to check if that key is there, and delete it or ignore it. I need a recommendation of what should be changed in the MSI file--I'm editing it using InstallShield Prof X, but I also have Orca installed... It's not a bug in SP1. Your uninstaller needs to call the ExternalApplication.UnregisterSolution OM method. Otherwise nothing happens on uninstall. Brian >I install a local Infopath trusted form using a msi file.

I didn't write the un-installer--it's the one InfoPath generated... I'm trying to figure out where the bug is--why it doesn't unistall completely... That's a little strange. The SDK tool should generate the correct uninstall script. Hopefully someone else here knows more about MSIs to tell you what to look for. Or if you do, it's the ExternalApplication.UnregisterSolution call I mentioned earlier. Sorry I can't help more.

It is removed from the Add/Remove software list, but something is left in the registry that prevents reinstall... I think it might be the "Recent Templates" key under InfoPath. If the form is listed there, then it won't reinstall. Yes, we think we've found the issue. It is around multiple isntallations of solutions with the same name. Try this to workaround: Register another solution with the MSI, then go copy the hidden custom action file. When you uninstall one, you can just replace the custom action file again and uninstall again. Thanks, Brian > it does uninstall it--but not completely.
