"Analia Ff", please see your private message s regarding an important administrative matter.
Also, I move your post to a new thread; that seemed more reasonable than resurrecting a 9 year old thread.
Did the error message appear in the command prompt, or in a dialog box? If the command prompt, did you post all of the text? If a dialog box, could you capture it (ALT-PrtScn, then post into Paint and save) and attach it to the post. I have a feeling that there is some extra piece of information missing.
Also, which version of Windows? 23 or 64-bit?
And is Visual Age version 2.0? That version is ancient (the Amazon page for it says it runs on Windows 95!!! Are you perhaps running a 64-bit Windows? If so, I suspect that Visual Age 2.0 is 16-bit and thus it will not run.
