I would like not to have to log in as an admin every time this certain program runs
Usually NO program does need admin-rights to run...
So are you sure that the program is properly installed, to the C:\program-folder.
Or is the program a proper Windows program at all??
Please tell us what program you are dealing with, and the search path it is installed to!
And NO! Do not use the build in Administrators-account, it has been deactivated for a reason..
If you enable it you will shortcircut every security feature that is built into a modern Windows!
That will only cause MORE problems later on!
