Ok - I've added some extra information to the GitHub description of the
alternative installation method:
During the ordinary Qgis installation two dll - files is copied to
directory C:\Windows\System32. The files are Microsoft basic support files
that is used by Qgis. To ensure that the files are present in subsequent
Qgis installations the files has to be copied from C:\Windows\System32 to
the Qgis program directory, subdirectory \bin, ex. "C:\Program Files\QGIS
The names of the two files is msvcp120.dll and msvcr120.dll, if the version
of Qgis is 2.18. For earlier Qgis the names *might* be msvcp110.dll /
msvcr110.dll or msvcp100.dll / msvcr100.dll.
NB! If a Qgis 32 bit version is prepared using a Windows 64 bit PC, the dll
files has to be copied from directory C:\Windows\SysWOW64 - *not*
I've checked that both QGIS 2.18 and 2.16 and Grass 7 are working if you
move the aforementioned dll's from C:\windows\system32 to the \bin subdir
of the Qgis program directory. So the method will work for these versions
of Qgis and Grass.
