In my Office-PC, I had Windows 7 Enterprise 64x Edition(Service Pack 1), and Visual Studio 2012 Premium Edition(not with the latest update). After spending sometime on the net, I found out that for comparing feature Team Foundation Server uses a file called “vsDiffMerge.exe“.If it was there, the location for the path would be
- 64bit – “C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE“
- 32bit – “C:\Program Files\Microsoft Visual Studio 11.0\Common7\IDE“
But later I found out that, “vsDiffMerge.exe” was not in the specified location.
The solution was to install the latest Update for VS2012(Update 3/4). http://www.microsoft.com/en-us/download/details.aspx?id=39305
After that All Is Well. File comparing feature will work smoothly.
