emultimedia (or broader) Errors - "missing MSVCR100" & other missing libraries/dll's

[magpiedin]

Some users recently got these errors when uploading different files (PDF, DNG, JPG) to Multimedia:

• "Cannot load MSVCR100 library" when user tries to open a module

• "Unable to load module ...\ImageMagick\...\coders\...dll"

Wiping/reinstalling windows remedied it, but uncertain if related to other software &/or network issues on local machines.

• Reinstalling DarkTable and possibly other software seems to bring back the MSVCR100 error.
