WMP Tag Plus's tag support currently never works in Windows 8, regardless of whether the error message is shown or not.Setting files to open with WMP doesn't affect tag support in any way. When installing a property handler, WMP will use that property handler for tag support instead of WMP Tag Plus.
I am using WMP 12 in Windows 7 Ultimate 64bit. Of course I am running the 32bit version of WMP 12 in 32bit as that is the default. After installing the utility (WMPTagPLus), I ran "Apply Media Information Changes" under Organize in hopes that WMP would then pick up and apply the tag info from my .flac files. Unfotunatly, this was not the case and my one .flac based folder (for testing purposes) remained unaltered afterword. Another note, I can play the .flac files and can even FF and RWD (which I had read some have trouble with).
If I try to open a flac by way of my UPNP server (Twonky) I get an error that this file is an unrecognized type and is unplayable in WMP.
WMP Tag Plus was only written with basic library usage in mind, and hasn't been tested with 'extras' such as streaming or syncing. Furthermore, because I personally have never streamed music from my PC, I don't have an idea of what could be the problem. If the problem lies with WMP Tag Plus, then I'm afraid that it will be practically impossible for me to fix it, as there isn't any way for me to reproduce the issue without a media receiver.One thing you could try is temporarily disabling WMP Tag Plus, and checking if the receiver is able to play M4A files then.Perhaps there are other people on this forum who know more about streaming, and will be able to help you better than I can. If there's a support forum on the Denon website, I suggest that you post this problem there as well.
Where is the wmplayer.exe file located on your system? (you can perform a search if you aren't sure)Are you running the 32-bit or 64-bit edition of Windows 7? If you're running the 32-bit edition, please open the Start Menu, type regedit in the Search field and press Enter. In the Registry Editor, navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\App Paths\wmplayer.exe. What are the contents of the (Default) entry there?

So I assume that means you're running the 32-bit edition of Windows 7?That entry should definitely have a default value set. Did you perhaps use a registry 'cleaner'?Adding the following .reg file to the registry should allow the WMP Tag Plus installer to find WMP again. Note that this file is for the 32-bit Windows 7 only:
is it possible in future to add support for the format mp3 (ID3 v.2.3 or better ID3 v.2.4) and wma, and video formats - avi, wmv, mkv ?
Why then does not want to edit the fields in the mp4 file All fields are inactive
For embedding artwork into FLAC files, you could use the tag editor of the Windows Media Player Plus! plug-in, or Mp3tag. Note that you will also need the just-released WMP Tag Plus 2.0 beta for FLAC artwork support in WMP.
