XDE "mfplat.dll is missing" solution

So if you have that problem then your Windows Phone Emulator won't start, and if you try to run it directly you have "mfplat.dll is missing" message, then there is solution that helped me.

Search your %windir%\winsxs directory for "mfplat.dll". It most certanly will find it in something like this, as on my Windows 2008 Standard R2 x64:

c:\Windows\winsxs\amd64_microsoft-windows-mfplat_31bf3856ad364e35_6.1.7600.16385_none_529f8a546d2657c9\mfplat.dll
c:\Windows\winsxs\x86_microsoft-windows-mfplat_31bf3856ad364e35_6.1.7600.16385_none_f680eed0b4c8e693\mfplat.dll

then take 32-bit version of it, and copy it into "%windir%\SysWOW64" ("%windir%\System32" for 32-bit OS).

The other way is probably to install "Desktop experience" feature (on Windows Server OS).
