>I've checked and I have administrative rights on my pc. Could it be because there is no reference to Windows 2000 in the case structure of the code for CASE ATC("Windows NT",OS(1)) # 0 in the init procedure?

I've seen this, but I really don't think it has anything to do with the problem. First, the DLLs are the same. Second, the main properties that are initalized (such as This.nCurrentOS) don't really come into play. What it's doing is defaulting to Win9x. If, for some reason, the system path was referenced in initializing the DLLs, then there'd be a problem. They use Win32API.

You might try modifying the code so that you can be sure that this doesn't come into play. I believe, from what I've heard, that OS(1) returns "Windows 5.0". I don't have a Win2K box to check, but it's simple to do. Just add and OR statement and check for that.
