Hi,
My windows boot drive corrupted on the weekend and I had to re-format and reinstall windows (windows 10).

I reinstalled my registered Mezzmo app, but when I go to media settings windows fails to install the service.

The system is vanilla, except for an installation of Malwarebytes,

I disabled Malwarebytes and windows defender (which is now apparently included in a vanilla windows 10) ...to no effect.

I also "fixed" the ownership of all files on my second HDD (where my media library resides) and ensured LOCAL_SERVICE and any authenticated user can access the library.

Mezzmo offers no error code but windows event viewer provides..
