I'm not to sure with win2000, but I think there is a way.
If program is loaded when in administrator. As you post says works in administrator.
Now in administrator, you will have to give access rights to other users (in this case user).
I wish I knew more on how to do this. But I'd start looking in the properties of the program you want to use and start there. I'm sure there is something in 2000 that will allow other users access.
Wish I could have helped more. But if you find answer, please tell how for others.
Oh yes, try using help. Look for granting access priveleges to other users.
My inputs for knowledge persuit.
