AdminServices Error - Could not read KofaxVersion or Version from registry.
One of the reasons why that error can occur is because the KofaxReg.xml has been corrupted.
Rename the mentioned file from C:\ProgramData\Kofax\Vrs
Run setup.exe from Kofax VRS installation media (previously used to install it on the station) to recreate that registry file..
