Unable to debug javascript in Visual studio

Question

I tried to debug my javascript but it doesn't fires the breakpoint.

I am using IE8 and VS2010.

On trying to add

an error occurs like;

I found that Tools-->Debugging-->Just In Time-->script is unchecked.

I checked it and saved....It remains unchecked....

I repaired my visual studio still issue continues...

The issue occures after i had installed VS2012
