Allowing syncro in safe mode

Does anyone have an updated script to allow syncro to run in safe mode? The one we have is getting the following error:

C:\Windows\system32>REG ADD HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\Syncro /f /ve /t REG_SZ /d Service
error> ERROR: The system was unable to find the specified registry key or value.

C:\Windows\system32>REG ADD HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\SyncroLive /f /ve /t REG_SZ /d Service
