problem connecting .net with access in 64bit
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,
