Problem with OLE Db Provider in Windows XP Media Center

Today I had a very strange problem with a .NET application that accesses a Microsoft Access database using OleDb Provider. The exception message was "unknown", so I was really confused. :)

I wasn't aware that the problem was related to database access until I tried to open a Microsoft Access database using Windows.

Well, after this introduction, let's see the solution:

Start->Run
regsvr32.exe C:\WINDOWS\system32\msjtes40.dll

This registers a Microsoft Access DLL in Windows Registry.

This problem occurred in Windows XP Media Center SP3 but I'm not sure if this problem is only related to this particular operating system.
