OLEDB.3.51 / OLEDB.4.0

Hi
I'm creating a database in code using ADOX. I set the OLEDB provider to version 3.51. On my development machine (Win NT Server 4/SP5), this works fine. On a test machine, Win98 (1st release) I get the error Class not registered. When I change the the version to 4.0 it works fine, but then I can't open the created database with Access 97.
Does anyone know how I can make sure that on the client machine OLEDB.3.51 correctly is installed so that is can open the database? It has to be openend with Access97.
Tnx in advance!
