You .NET configuration has been overwritten at some point by one of the oracle client installations.

The oracle installers can be a bit hamfisted with this file and don't always update it correctly

I recently had a similar problem when installing the Oracle Client for Microsoft Tools and all of my .NET applications were broken as a result!

If you navigate to the folder referenced (C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config)

You will see a number of Machine.Config.* files.

Check the timestamps on them, I suspect Machine.Config will have a different one from all the others. Microsoft give you a template Machine.Config.Default file that you can use to difference with Machine.Config to see what has been changed.

I you know what you did, you may be able to uninstall whatever it was you installed.

I had to over-write Machine.Config with Machine.Config.Default before I could run the uninstall as it used, guess what - .NET!
