Revit 2018.1 and Licensing System Error 1

A student experienced Revit 2018.1 giving him this rather useless error message:

Licensing System Error 1

After Googling for a solution, we installed/repaired all the Visual C++ runtimes we could find in 3rdParty\x64\VCRedist and in 3rdParty\x86\VCRedist from the Revit 2018 distribution.

Success!

Shame on lazy developers not willing to code reasonable error messages explaning what the program attemped to do with what.

GNU style error messages is a lot better than nonsense words. E.g.:

sourcefile.c: lineno: open("/some/file") = -1, errno = 2 (No such file or directory)


Update 2017-09-05:

Today I had the opportunity to examine another case of “Licensing System Error 1”. This time I installed 3rdParty\x86\VCRedist\2005\vcredist_x86.exe only. As far as I can tell, Visual C++ 2005 Runtime x86 wasn’t installed at all prior to my actions.
