Windows Media Player no longer plays MIDI files, other apps work fine

Whenever I try to load a MIDI file in Windows Media Player after installing VirtualMIDISynth, WMM gives the following error: "Windows Media Player encountered a problem while playing the file."

No matter which default device I have set, it always fails. I don't mind not having WMM as I always have other options, but this is quite bothersome. If anyone has a solution, please reply.

That's really strange...

Have you tried to uninstall VMS? Uninstall procedure is really carefull in resetting the system to the state it was before install.
Another try is to follow this FAQ and double check the suggested steps.

If you're able to fix it, please let me know what was wrong so I can fix VMS too.

Something is definitely rickety with WM_Player- see this post.

Same exact issue. Is there a way to debug WMP to give more info regarding the crash?

There's no need to worry about it for much longer. It's going to be pulled next rev.

Re: Windows Media Player no longer plays MIDI files, other apps work fine

Well, I'm worried. I don't use midi much outside of games but having something broken bugs my OCD.

It's not just WMP, it's PotPlayer, Media Player Classic...

The big problem is a standalone MIDIplayer would be nice, but I also want the default Microsoft soundbase, if ONLY because that's how I grew up listening to some music.

Not sure if there's a way to reinstall the MIDI side of things. Here's the Potplayer error.

AFAIK, those players are all DirectX-based players, so they use the same media layer as WMP.
Maybe you could try to reinstall WMP: search Google for "Media Player disappeared after Fall Update install" and follow the instructions on how to reinstall it (sorry, I'm away from my PC, replying with mobile).

Also, have you followed my suggestion in 2nd post of this thread?

Uninstall and reinstall did not fix the problem.

Registry tweaks seem to have no effect.

I also have midimapper settings keyed to midimap.dll

I've had a very similar issue on my development machine a few days ago.
The strangest thing was that the error appeared only on x86 MIDI players (mpc-hc.exe) and not on x64 ones (mpc-hc64.exe, wmp).

After trying a lot of things, I solved it by re-registering quarz.dll and xxx with regsvr32.exe.
(see here for details: http://codecs.forumotion.net/t1339-mpc-doesn-t-play-midi-and-wav-files)

Open an administrative command prompt and run these commands:

regsvr32 C:\Windows\SysWOW64\quartz.dll
regsvr32 C:\Windows\SysWOW64\devenum.dll
regsvr32 C:\Windows\System32\quartz.dll
regsvr32 C:\Windows\System32\devenum.dll

One or more of them could output warnings or errors, nevermind and go on.

Hope it works for you too...
