Access 2003 error message

Hi.

Only one computer I get error message: Runtime Error 430
Class does not support Automation or does not support expected
interface

I have vba code in my access and all reference-files and versions,
looking from VBA, are exactly the same as in the computer which works
perfect.

I have looked via google hundreds of cases, but nothing has helped.

Computers have XP PRO.

Help me!
