I'm running windows 7 ultimate and am trying to install some software off of a secure server at a remote location to my hard drive. The install fails every time because the my user account (an administrator) does not have full write permissions to the program files directory. I have tried taking ownership of the directory, but I don't have permission to change it from TrustedInstaller. I turned on the built in administrator account and logged in through that, but there is no difference in permission level. When I attempt to change the permission level I get the following error dialog box: An error occurred while applying security information to: C:\Program Files (x86) Access is denied Then the following: Unable to save permission changes on Program Files (x86) Access is denied. I've been fighting with this for three days now and I consider myself pretty adept at typical windows bs. Yes, my UAC is set all the way down. That was the first thing I turned off. I also tried shutting down virus protection and firewalls to no avail. Any help here would be awesome since none of the posts I've been able to find say what to do when the admin can't take control from TrustedInstaller. Many thanks to whoever can help me out on this!!!
