Hi,

I have a windows form app which works OK on XP but when I try to run it on WIN 7 I got this error below. How can I fix this?

Well, it looks like you're trying to open a registry sub-key without having the necessary permissions to do so.

If you're not doing so already, I'd try running your application as an administrator.

The first thing to do is to fix the program so it catches the error instead of crashing. You can do that using try/catch. You could also add code to check to determine that the program has the privileges it needs, and the program can show a useful message if it does not have the privileges it needs.

You should also ensure that there is a valid reason for requiring administrator privileges. Security personnel would advise us to not use or require use of a privilege that is not needed. Don't automatically give or use a privilege just to get something to work.
