Barely any of my games will recognize Vista as an operating system. I have tried running programs as admin and as XP under compatibility tab. Getting missing d3dx9_25.dll error, downloaded copy, now Vista cant find it. My Pc is E-machine W3609 3.33 GHZ 512 ram Nvidia GEforce 7300 gs and wish I could have my XP back, or the update that fixes all the problems I'm having trying to run my games. I couldnt even load intellepoint 4.1 because of known compatibility errors. Please help.
