"Unrecognized database format" error

[PaulA]

I have a split 2003 (.mdb) database accessed via 2007. Our users suddenly started getting a ""Unrecognized database format" error apparently for the backend database only. I tried to open it in 2010 and I get the same thing.

I have made no changes that would bring this about.

Any ideas of what is going on? This houses our data (although we can get an archive file if needed).

Thanks!

Did you try a
(a) 'Compact & Repair' on both front and back ends?
(b) Relinking the Back end?

This is because there is currently no 64bit version of the Access driver, only a 32bit version . You could try to run the .exe as a 32 bit (Wow64 application) process on the 64 bit machine:

1. Right click your project and select Properties.

2. Select Build and select x86 in the Platform Target dropdown.

3. Save, Rebuild and run you project, you should now get the rows for the table.
