Highly recommend downloading the latest version. This was fixed in 2.71.
Version 2.70 loads libeay32.dll which has a VC++ 2013 x86 runtime dependency. The
0xc00007b error means it is trying to load the x64 runtime library and the library is misconfigured.
The msvcr120.dll missing error means the runtime library is not installed. In either case, the
solution is to download the x86 VC++ 2013 x86 runtime library installer and let it correct
the problems. Download the x86 installer (vcredist_x86.exe) from Microsoft and run it:
Our installer includes this runtime library and starts it if we detect that it is not installed.
We cannot, however, detect a misconfigured installation so you may not have had the opportunity
to use the runtime library installer when you installed the Managed Switch Port Mapping Tool.
