Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine

I run Windows 7.0 Ultimate on a 64 bit PC. My C# WinForm program runs fine in Debug mode. But when I switch to Release mode, somehow trying to open an Access databae throws the following exception:

"Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine"

Any idea?

Thanks,
newbieweb

P.S. I was supposed to release this today. I never thought I needed to test the Release version...
