Packed distributed libraries in the MCP2210DLL_2014-10-29.zip package are
msvcp100.dll and msvcr100.dll but MCP2210DLL-UM.dll requires MSVCP90.dll an=
d
MSVCR90.dll . These two were removed by Microsoft and replaced with
msvc?100.dll in 2010, as a part of the famous update which caused about hal=
f
a million windows users to be locked out of Excel and Outlook by installing
that update. Reference:

msvcr90dll/4f76e16c-e404-4685-9934-94818b1cf72c
.. I infer from this that Mchip either compiled the dll on a non updated
windows system from before 2010, or did not update the dll when generating
the 2014 release package. Neither of these two possibilities is very good
imnsho. I would suggest mchip walk their dlls with DependencyWalker.exe or
similar before upload and weed out any onsolete or dangerous references to
old dlls. Reinstalling MSVC?90.dll to make MCP2210DLL-UM.dll work now,
basically reinstates the bugs fixed by Microchip in 2010. Not a good move o=
n
any computer, especially not on a development machine.
Opinions, flames etc. welcome. Thanks.
