I have run into this numerous times, so I am hopeful this will help someone, and also be a good place for me to look if I forget what to do.

At my office computer, I have taken advantage of the ease with which you can use Folder Redirection in Vista. In XP it was a bit harder, but with Vista it is easy to have the “Documents” (no more “MY” in Vista) stored on a network share, in my case one that is RAID enabled so I won’t lose my stuff.

Anyhow, since that redirection changes the Registry location for user files, it has messed up many of the programs I install that use InstallShield to install. InstallShield doesn’t apparently like UNC or Mapped drives as locations for personal/temp files, so I get this Error 1327 Invalid Folder.  I found this doc on their site and it was for XP, but the same fix applies.  Basically, I change the Registry entry that points to the invalid mapped drive, and run the install, and then add back in the registry key (or you can also just set-up the redirection again).

These vendors need to realize in more corporate environments, esp. with the advent of Vista, this redirection is more likely, but at least I found a workaround. It is annoying, but no at least I know and it is pretty easy to do.
