Vista - Program permissions

I have tried everything so now elevate my problem to you guys.

On my Vista ultimate platform I have two users, a real admin and a user with admin rights, I have a program from Canon that will only run in the user with admin rights setup not the full admin mode!

I have looked at the permissions for this file and there are two major differences that I can see, in the user mode it has Trustedinstaller and my user with 'Special Permissions" set these are not present in the Admin user mode.

The program was installed in the full admin environment.

In user mode I am asked to confirm the program start up, in admin mode I'm not asked but get an instant message "ZB module has stopped working" and the program looks for a solution but never finds one.

The program is Zoombrowser and is the latest version and Vista compatible, clearly it does work.... just not always!

Any thoughts would be appreciated

Not that anybody cared! but I'll post a result here in case any other poor sole has a simular issue.

I managed to set the file ownership to Trustedinstaller, that seemed to solve the problem, on the other hand it could have been a bunch of new updates MS pushed.

Bottom line it now works.

I Care!!!!

I think I'm having the same problem. The person who installed the program can run it, others, including services cannot! how do you set the file ownership to TrustedInstaller?
