Windows 8 was released by Microsoft in October 2012. Windows Media Center has become an add-on, but is still available for Windows 8.
Unfortunately, the current vmcMote server, version 18.104.22.168, does not work properly with Windows 8. It is not correctly handling the new .NET framework 4.5 in Windows 8.
I finally fixed those issues and created a new server, version 22.214.171.124, that works with Windows 8.
You can download it here: Download vmcMoteServer 126.96.36.199 BETA
It's still labeled as BETA, as I did not found the time so far to test the new server intensively. Any feedback is appreciated.
