This is actually weird as we should not use msvcr120.dll at all.

Can be closed as a duplicate of #8337.
Because it is about C:\Program Files (x86)\Trusteer\Rapport\bin\MSVCR120.dll which was mentioned in

But what about to investigate the difference in usage of MSVCR100.dll and MSVCR120.dll (as Mozilla has MSVS 2013 as the minimal supported version)?

I just checked our firefox.exe and it is correctly dependent on msvcr100.dll being around. Thus, this is just a duplicate of #8337.
