Attempts to install Skype for Business 2015 Debugging Tools* on an administrative workstation or server running a supported Windows OS may fail with the error:
Skype for Business 2015, Debugging Tools installation or uninstallation requires that Microsoft Visual C++ 2013 x64 Minimum Runtime – 12.0.21005 Package is already installed. Either use Setup.exe for installation or run vcredist_x64.exe included with the product to install the redistributable.
[ OK ]
You can either ensure that …
… the target machine has completed running setup.exe from the Skype for Business Server 2015 media, which includes the prerequisite VC++ 2013 runtime that you must install anyway, or install from a downloadable copy of the Visual C++ Redistributable Packages for Visual Studio 2013#.
Note that unlike in Lync Server 2013, a “Lync-specific” version of the latter does not appear to be a requirement.
