I have to install the driver for DFG/USB2pro Video2USB Converter [1] silently (SCCM).

For any oher driver I used before dpinst.exe /s works very well.

I used dpinst /S /F /C and the output is:

INFO: Returning with code 0x8001000

According to this [2] it means "One driver package was present, but it could not be installed"


If I just ran dpinst.exe in window mode the message "Are you sure you wanne install softwarefrom The Imaging Source...Company" appears and if I check the box "install everything from this vendor" and hit "install" the driver will be successfully installed.

I also tried /LM but its the same issue (WARNING:DRIVER_PACKAGE_LEGACY_MODE flag set but not supported on Longhorn. Flag will be ignored)


System is Win7 x86.

Sorry for my bad english.

First of all check that the vendor's certificate (the one they used to sign the driver with) has not expired.

then I think you might need to add the vendor's certificate to the trusted publishers store to avoid those "are you sure you want to install software" warnings. Incorrect or incomplete signing of drivers is always gonna pose problems on any Windows version greater than XP.

    So it seems thats the cert is valid... (if I checked correctly)

    If I export the cert from the .cat file and import it to trusted publishers the silent command line intsall is working but thats not really handy if I had to publish the cert in the AD-environment.
    Nevermind what happened if the driver should be updated...

    Thanks anyway...
