If you get this above error message on Windows 7 64bit computer.
I fixed this error on my computer by assigning full control or modify permission to my username for the machine.config file that was giving the error message.
Follow the instruction bellow to change the permission of this file:
1) Navigate to the folder
c:/Windows/Microsoft.NET/Framework/64v4.0.30319/config2) Right click
machine.config and click
Properties3) Click the
Security tap4) Click
Edit and then click
Add5) Type your computer
username and click ok
6) Select your username and check-off
full control in the permission pane

7) Click ok to all the open windows
Same fix applies for the 32-bit operating system but file is in different folder root.
