[SOLVED] Pipeline Tool is not working anymore - Importer 'FbxImporter' had unexpected failure!

Hi Everyone,

I would really appreciate if anyone can help me with this issue, because this is getting on my nerves really. I have joined the Windows 10 Insider program at the beginning in April and I began to develop a game with Monogame. Since then, everytime Windows 10 is upgrading itself, the Monogame Pipeline tool is not working anymore. It gives me the folowing error message:

Importer ‘FbxImporter’ had unexpected failure!
Assimp.AssimpException: Error loading unmanaged library from path: Assimp64.dll, see inner exception for details.

The only solution I have found is that I download the newest Windows 10 ISO and make a clean install, and then reinstall everything and then everything works again … until I receive a new Win 10 upgrade …
I think I made at least 10 clean installs in the last 5 months and I am sick and tired of it. Simply reinstalling Monogame is not solving the issue.

Does anyone ahve any idea?

Thanks in advance!

I have found solution = (re)install Visual C++ Redistributable 2012:
