Unfortunately it ain't working on my Windows 8 native installation, but it is good to know, that it is possible.
p.s. I tried MP2 on my Windows 7 desktop and it works extremely fast
Running in Windows 8, I needed a reboot after the DX9 Runtime installation and everything went fine
Here you can find a working "MP2-Only version" https://forum.team-mediaportal.com/threads/ir-server-for-mp2-only.106329/Which IRSS version to use with MP2?
A Reboot in the middle of the installation is quite ugly so this has to be handled better by next versions of the installer, I think.
