I've got an installer that could run on both Vista or XP, and I'm having a problem with a registry entry.
If I add a value into the Current User/Local Machine when I try to install on Vista, the error is:
Could not open key: UNKNOWN/software/...
Verify that you have sufficient access to that key or contact your support personnel.
This error does not occur on XP. If I change the location to HKEY_USERS, it works just fine in Vista, but complains in XP.
