OpenFile & WriteFile hunc when logged in as user?

A user of my application found a problem when he was logged in as user, not adminstrator.

But I have trouble to use ReadFile (can not even open it) and WriteFile to work, even when I used relative path on, that pointer to a subfolder (or a subfolder).

Can this maybe the problem, why some games need to logged in as adminatror before get them to work?

More likely, the user in question has not been granted read/write permissions in the folder you're pointing to.

That would be an operating-system level limitation, not blitzmax. (The fix most likely would be to log in as administrator, and grant the user read/write access to the folder)
