Scanner error Windows 10 with LMS 7.9 and 7.8

I have done a win 10 update from a fresh install win7 with no applications.

The first Program was LMS.


Now I'm not able to scan my Music Library. I have tried LMS LogitechMediaServer-7.8.1-1438696600 and Logitech Media Server-7.9.0-1440053825. In both cases the scanner stops after a few secons with the same Errormessage (on different files)

The second problem is, the LMS is not recognizing my piCorePlayer. I have rebooted the little piCorePlayer many times, but no Player appears in the selection.

Did the LMS only looks for Players when the scan was successful?


Any hints? Thanx...
