Microsoft.Jet.OLEDB.4.0 not registered with IIS
The web page worked fine in testing, but after publishing, I ran into a problem with an Access Database driver.
Error: The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.
It turns out this is a 32 bit driver. You will need to go into IIS, and set the advanced settings of the Application Pool. Set the "Enable 32-bit Applications" to True.
