May I know the error message thrown by dll atl100? Did you install any add-on for Visual Studio? What if you create a simple winform or console application using Visual Studio, and then launch debug session by pressing F5?

Hi

I believe you would have found the solution already for this. 

Still, I am adding a solution which worked for me. Hope it helps someone

I was working on a solution and all of a sudden today morning I found this error:

 The version of clr.dll in the target does not match the one mscordacwks.dll was built for.

Searched for some solutions and I came across some links which asked me to install VS 2010 SP1.

Now it is working fine.
