Not able to start WDFVerifier.exe RRS feed

  • Question

  • Hi,

    I am developing UMDF2.0 windows driver using WDF. I tried to install the driver and I was successful. After installing I opened wdfverifier.exe and attached WinDBG for user mode debugging. I disabled and again enabled the driver to attach to WinDBG. When I did that multiple pop ups of WinDBG opened. It did not stop. So I forcefully restarted my PC and BSOD occurred. After this I am not able to open WDFverifier. Whenever I try to open that the following error comes. 

    An unexpected and fatal error has occurred -details


    void __cdel AllWdfDevices::AddUmdfDriverTo(struct

    _DO_DEVINFO_DATA & class wdfQa::Common::ObjectArray &)

    Error 2 <2> encountered

    System Message : The system cannot find the file specified

  • Have you tried the procedures documented here: the easiest way is to run AppVerifier on WUDFHost.exe

  • Thank you for your reply. Actually I was not followed the procedure which is mentioned in the link. First I installed driver using devcon.exe and I opened wdfverifier.exe and attached host process of my driver to WinDBG. After that multiple pop ups of WinDBG came and BSOD occurred. If I want to follow the procedure mentioned in the link I have to open the wdfverifier.exe ryt? I am not able to do that. Also AppVerifier and WinDBG are same?

  • For UMDF it is a different verifier.  AppVerifier is an application verification program, so depending on you UMDF driver it will actually check more things than just using the umdf verifier.
