Trying to deploy Bighand via GPO MSI , running the System App Via the Transform brings up the below error

That error relates AD authentication, but because you are using BigHand Professional, this should always be turned off.

Browse to – 
[HKEY_LOCAL_MACHINE\Software\Bighand\Totalspeech\v3] 
(on a 64 bit machine this will change to [HKEY_LOCAL_MACHINE\Software\Wow6432Node\BigHand\Totalspeech\v3]) 

The REG_DWORD to look for is called “AuthenticationType” This should be set to “0”
