I'd be tempted to remove the functionality altogether if it's easier than fixing it. I don't think that it's a very commonly used feature.

The functionality has been already removed from MM5

Re MM4 status:
Previews can be WMA only and because of the recent WMA encoding issues (after Win10 Anniversary update) it would probably makes sense to remove it from MM4 too.

Currently it fails (also on Win7) in EncodeWMAFile, last lines in debug log:
[1576] EncodeWMAFile - calling WMAWriteStreamInit
[1576] Calling iWMAWriteStreamInit

Really also in Win7 with old WMCore libraries? This error in WMAWriteStreamInit (exactly in calling WMCreateWriter) was introduced in Win10 Anniversary update.

It was caused by some parameters in MediaMonkey.ini.

Once I modified the preview WMA format then it started to work and works also in the default config. I do not have backup of the old MediaMonkey.ini so I cannot replicate anymore (to see which params were bad for the encoder).
