WMA encoding fails on Windows 10
Updated by Russell Samuels on Feb 15, 2018

The Windows 10 anniversary update (aka Windows 10 version 1607 OR build 14393.xx) introduced a bug that results in failures in WMA/WMV encoding.

As of Beta and newer, we introduced a new "WMA (Win 10)" encoder that is compatible. The latest MediaMonkey Beta can be downloaded from

Alternatively, another workaround is to copy "WMVCORE.DLL" and "WMVENCOD.DLL" from the "system32" ("sysWOW64" on Windows x64) folder in Windows 10 version 1511 into the MediaMonkey for Windows main installation folder and restart MMW so that those files are used in WMA encoding.
