i had the same problem and I noticed it was installing it in Appdata.. so I changed the location to install it in C:/ProgramFiles/LIVE (I created the LIVE folder because when I tried to install it in Program Files, it said that folder already exists, which it didn't...)
    After installing it to C:/Program Files/LIVE
    my LIVE 8 works fine.
    You can also install it to Program Filesx86/LIVE.
    I hope that helps.
