Comment (by johndoe):

 > The first off, the numbered versions are a component of the newer Visual
 Studio C++ Runtimes. Hence the versions. Each release is tied directly to
 a visual studio release. We do not have the rights to redistribute these
 files

 Well, I think you do. Not only vc-redist installers, but even separate
 files, if you need.
 According to https://msdn.microsoft.com/en-us/library/ms235299.aspx:
  It's also possible to directly install redistributable Visual C++ DLLs in
 the application local folder, which is the folder that contains your
 executable application file.


 > See ​https://msdn.microsoft.com/en-us/library/abx4dbyh.aspx You always
 need a C runtime.

 But MSVCRT.DLL is not C runtime:
 https://blogs.msdn.microsoft.com/oldnewthing/20140411-00/?p=1273
 So linking to it is against MS guidance.

 But ok, I am not going to make holy war from it.
 My problem is that in my system MSVCRT.DLL just does not contain required
 exports (but 'numbered' msvcr90.dll does)
