Error: Microsoft.Jet.OLEDB.4.0 Provider Is Not Registered

This error deals using Microsoft Access as a database for a program that is running under Windows 7 64-bit.

Microsoft Access does not run on a 64-bit platform which led to this error.

We just have to force the program to run in both 32-bit and 64-bit platform.

Here's how.

Click the window icon located at the lower left and type INETMGR.

From the IIS manager, select the Application pools. Select both pools than click advance settings located at the right side.

Once clicked, switch the "Enable 32-bit application" to TRUE.

And viola, that's it.
