Installation Troubleshooting

In case there was an error in starting VDM services, there are 3 options:

  1. Reinstall VDM (reboot required)
  2. With existing installation re-run VDM service registration via VdmSerup.exe utility
  3. Use SC.exe command with existing installation present

[1] is self-explanatory.

[2] Steps with VdmSetup.exe using command-line (elevation is automatic):

Unregister and register service from “C:\Program Files (x86)\VDM\System32\” folder for 64-bit windows, “C:\Program Files\VDM\System32\” on 32-bit.

    VdmSetup.exe -u
VdmSetup.exe -i   

#3 is the most comprehensive, though the most reliable. Here are the steps:

Stop and delete service VDM related service.

    SC STOP TeknicaVdmSvc
SC DELETE TeknicaVdmSvc   

Register VDM service again and start. Make sure to keep all quotation marks as prescribed.

    SC CREATE TeknicaVdmSvc binpath="\"C:\Program Files (x86)\VDM\System32\VdmSvc64.exe\"" displayname="Teknica VDM Service"
SC CONFIG TeknicaVdmSvc start=auto
SC DESCRIPTION TeknicaVdmSvc "Teknica VDM Service"
SC START TeknicaVdmSvc   

As mentioned at the beginning, installation issues can be related to Antivirus “FALSE POSITIVES” behaviour. Make sure to check that all VDM service files are located in “C:\Program Files (x86)\VDM\System32\” folder on 64-bit Windows (“C:\Program Files\VDM\System32\” on 32-bit) and were not removed by local Antivirus software. All the files should by signed by Teknica Software Inc certificate with additional Microsoft signatures for “*.sys” files. Here are all VDM service related files at the time of this writing:
