Access2000 vs VB5

Hi I'm new to the forum...

I Built a 3 table key tracking db in Access2000. The boss wants a
quick access application just to do key profile entry with a clerk
that's not too savvy about the Access front end. I did a little exe
in VB5 and it flies nice on the local xp machine but on the NT network
machine I keep getting a co9nflict noting that 'its' looking for a class
ID for the registry. What do I do next? (Not a clue) ...Thanks

Did you properly install your app or just copied exe and msb files over to some shared folder and then on the user's workstation created a shortcut?

VB5? That's pretty old. There may be stuff that's no longer supported, but since you say it runs on XP, maybe not an issue.
Check for references on the trouble machine.
