OLE-Error 800 40 112

If created a application which is connected to a Access 97 Database.
I installed this application on 4 PC's without any problem. But on one
PC I can't get it working. as soon as the program tries to connect the
DB I got this error "OLE-Error 800 40 112". I haven't found this message
nor the errorcode in the help file. Any idee what the problem could be?

Thanks for response
