Thread: CLASSPNP.SYS blue screen CRASH after install 3.41 (updating from 3.20)

    Default CLASSPNP.SYS blue screen CRASH after install 3.41 (updating from 3.20)

    Operating System: Windows XP SP1 with all criticial updates
    Burning Software: Alcohol 120% latest version & Nero 6 Ultra edition (not using easy cd)
    Anti-virus Software: Norton 2003
    DAEMON Tools Version: 3.41

    hi all.. just want to inform u that the new Daemon Tools 3.41 crashes my system with CLASSPNP.SYS driver error. At first it didn't boot in Safe mode either. Then i did "Restore last known good settings".. the system booted, but crashed while loading daemon tools. It did enable me to do safe mode boot finally! after doing system restore my system is back to normal running version 3.20.
    I think it could have something to do with the Alcohol 120%, since it has a virtual drive too.. however version 3.20 and alcohol 120% seem to work together perfectly.
    just a guess: It matters which one is installed first???

    Do you have minidump (in windows\minidump folder) we can check?
