I am sorry to say, but the information that you have provided is not enough at least for me to make out what is wrong with your project. You can do one thing however. See if the client machine has DCOM 98 installed. If you are using ADO with VB 6, I think you definitely require DCOM 98 on the client machine.

Also, instead of giving the Win OS Version info, try to give details as the data components used in your project, the components installed on the client machine etc.

(I really hope I can solve your problem, now that you want me to take you as my brother!)
