After a suggestion that Gem might be lacking certain Microsoft Visual
C++ libraries in Windows10 installations I am trying to track down the
exact name of the required libraries. I am unable to find that
information from the mailinglist archive. It would be great if someone
who has/had the same problem could help us out here.

Thank you for all ideas,
Peter
