I own the original version of GPO and haven't used it for years. I just tried to install it and failed. I got an error message saying:

"Error creating file.
1008:5,-5000 Access denied error"

I then got:

"You do not have enough access privileges for this installation".

I am using a 27" imac, Mac OS X 10.6.3

I am the administrator and have attempted repairing disk permissions.

Anyone know what i can do to complete the installation?
