I installed the first X game on Windows 7. When I run the game, nothing happens. In Task Manager I can see runme.exe and X.exe running, but still no game. I tried to run it also as an administrator, no effect.

Any idea? I'm using Avira Antivirus, in case it is causing some problem.

Works now after a reboot. I don't know what it was, at some point it seemed that Avira was the culprit because I could get it to run after disabling realtime protection, but now it works also with it enabled.

I don't have such audio issue, music seems to work fine both in menus and gameplay. This is a relatively fresh Windows 7 installation where I haven't installed any extra audio codecs or such by myself (because in the past when I used to do that, I used to get odd audio problems in different applications and games, like watching some video and the audio levels and balance were all wrong...).

However, I think that in the audio options to audio was for some reason targeted to SPDIF digital audio for some reason. I changed it to default audio. I had this issue also in Descent 3, where the whole game was first silent because it was using SPDIF by default, but changing it to default sound fixed it and now Descent 3 sound works fine too.

I can hear it all, just the music is messedup. It's outputting correctly or I wouldn't hear it.
Might be a codec problem, yes. But it's strange because I can hear the music fine if I open the .dat audio files that are in the mov subdirectory with MPC-HC.
