So, no moderator approved my thread yet!!! After almost 4 days.
I installed Win7 instead of vista, because I hear MicroSoft repaired driver
and application compatibility problem in Vista by releasing Windows 7 which supports all programs and drivers
I installed the WLM8.5 and modified compatibility to win2000, but the same problem "We are unable to run audio & video setup" occurs.
I thought vista sucks, but also all the BOOM PUB press made to win7 was a lie. Compatibility 0 same as Vista. My Pinnacle TVSAT driver and app aren't supported, and no supported drivers on net yet. My Canon LBP-1120 driver isn't supported. WLM8.5 cam can't load. What's better in Win7 than Vista? I see they're the same.
My only choice yet is to go back to XP, because even my first thread isn't published to let me get help from visitors.
I'll go back and enjoy the cam and all the applications I need with no trouble.
