    Default [4.12.4] unable to add adapter device problem 39

    Cannot find Virtual Device Driver
    Unable to add adapter device problem 39

    Windows XP SP2
    Daemon tools 4.12.4
    SPTD 1.56 - comes with Daemon Tools
    Windows XP Service Pack 2

    Verify SPTD is running. Open Device Manager select View-> View hidden devices. Check under Non Plug and Play devices for spdt device. It should be running. If it is not then re-install SPTD.

    When Daemon tools tries to start you get the error message as above as it cannot talk to the SPTD adapter.

    IBM Proventia eSecure or IBM Desktop security is running and blocking access to the device. It doesnt seem to matter if application security is turned off.

    1. Right click on the Proventia icon in bottom right corner and select Stop Agent.
    2. Start Daemon Tools
    3. Right click on the Proventia icon and select Start Agent.

    If you have feedback on this solution please reply to this thread. If you have an alternate solution for this version of DT then please post a reply to this thread so we can collate them.

    Just got the same problem - 39

    I changed my SATA mode from IDE to AHCI, so I renstalled Windows XP SP2 to SP3 by occasion. After that DT 4.30.1 start getting error "unable to add device problem 39". I tryed removing DT , installing old versions, nothing helps. I see in device manager how it tryed to add SCSI device - shows for a sec and gone. I have no other scsi device. I`m using nvidia 780a chipset, Win XP SP3 (under Vista 64 on the same comp it works fine). Maybe there is extra cleanup need to reinstall DT ? I tryed to remove setting from previos installations.

    p.s. I reinstalled WinXP in repair mode (if it means something)

    Try a clean install of Windows XP.
    Make something idiot proof, but then they just make a better idiot

    99% it will work on clean install - I have no doubt - but its not a solution in my case - I need to understand what can cause problem. Overlooking exisiting drivers in my system - remove unused. Maybe permissions problem or something in registry ?

    checked drivers in \system32\ folder - not help - problem is somewhere out this folder - any registry setting DT using ?

    p.s. Tryed to install 4.06 - found interesting thing - when DT starts adding device ...device appers in SCSI/RAID controllers....disconnecting sound..."SCSI/RAID controllers can now be safly unplugged" pops out ....adding device problem 39 error. Looks like something ejects DT virtual controller

    This problem can be caused by faulty filter drivers in your system installed as part of some RAID package.
