Fences Configuration Parser Error

After a system restore, Fences started to issue error messages saying there is a configuration problem

with dot net. I tried updating dot net from its website, but it is still showing the error messages. 

I am guessing there is some configuration I have to do to restore what was there before the system restore. 

Does anyone know how to fix this?
