The new key is called "AcknowledgedRunningOnAppServer" and is of the DWORD type. It must be set to 1 to enable the services to start. The paths on which the key must be set are as follows:
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server\version\LauncherSettings
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server\version\LoadBalancerSettings
- The placeholder version represents 12.0 for SharePoint Server 2007, 14.0 for SharePoint Server 2010, and 15.0 for SharePoint Server 2013.
- Unless the registry keys are set for each document-conversion service (Launcher and Load Balancer), the services cannot start.
