From what I can tell by running dscacheutil -q user, the Toast installer is setting user id 501 as the owner. This is fine assuming that there is only one user on the system and that you happen to be a user with uid 501. Unfortunately, uid 501 on my systems belongs to an Apple Remote Desktop user account. So I now have to go around and manually change the permissions so that all users on the system can access the program. Interestingly, the installer asks that question (install for all users) yet doesn't set the permissions so that all users can access the program.
