Hi,
I have created a quite big web application in a windows 32-bit system with c# that uses an access database with the jet engine (4).
Lately, we have to move the whole thing to a new 64bit server - with windows 2003 64-bit.
The aspx pages work fine, but wherever I try to open the mdb it fails with a message that ole.jet engine is not registered on this machine.
I searched a bit and I reinstalled mdac 8, but no luck at all. I also tried to install some service packs for jet engine (64bit) but it always says that it is not for this hardware.
When I try to check the odbc drivers it also displays only the sql and displays an error (that it is not installed correctly) for the access (*.mdb) configuration.
What do you suggest?

I cannot (at least right now) rewrite the application to use sql server.

The new pc has two 64bit intel (xeon) processors.
Thank you very much,
Nick

Nick:
Have you tried using MS Access 2003 to access your database (.mdb)? This reminds me of MS Access Upgrade 2002, in which at the point of opening the DB, you were prompted to convert the database. Sounds as if this could be the case. If you are successful, use the documentation utility against the tables.

Hope this helps.
