• Here is the workaround fix this problem:

1. Uninstall WinFx Beta 2.
2. Uninstall the WIC redistributable package by running: %windir%\\$NtUninstallWIC\$\spuninst\spuninst.exe
3. Reinstall WinFx Beta 2.
4. (optional) Verify that WindowsCodecs.dll and WindowsCodecsExt.dll are in %windir%\system32.

Thanks very much to Fritzenhammer for testing this workaround for us.
