When attempting to uninstall or Upgrade Device Web Service (DWS) on a system where it has been installed on a drive other than the C Drive, the process fails and cannot complete.
When the uninstaller is checking for the application location, it only searches on the C drive and therefore the process fails.
To workaround this, the files should be copied to the C drive (leave the original files on D) - C:\Program Files\Kofax\Shared Services\DWS
The software will then uninstall from the D Drive correctly. The files can then be removed from the C Drive.
