Microsoft SQL Server Management Studio not working after installing .Net Framework 4

Question

Yesterday I installed .Net Framework 4 as it was required by Liquid XML Studio, but just after installing it, My SQL Server Management Studio stopped working. As soon as open the IDE I get

package microsoft sql management studio package failed to load

I tried pretty much all the solution posted on the internet but could not get it working, today when I removed the .Net Framework 4, SQL server management studio started working again.

Then just to test, I installed the .Net Framework 4 back ... and I started getting the same problem in management studio.

I want both on my machine ! how can i do it ?

PS : OS is Windows 7

Solution

Seems like it was looking for the following registry key and not finding it.

HKEY_CURRENT_USER\Software\Microsoft\Microsoft SQL Server\100\Tools
