We have recently installed Version 7.6.2.9999 Design onto two new Windows 10 machines. We can see our Production server from these Design seats and the Production server can also see our new Design seats from the Access manager. However nothing happens when we try to send-to-Production.

Messenger is running fine on the Production server and can receive files from an older Window 7 Design machine.

It appears messenger will not start up on the two Windows 10 machines though. Firewall is shut off and ports are open just like the Win 7 machine. The Win 10 machines and Production server can all ping each other.

When we try to start messenger on the Win 10 Design machines we receive this error:

Windows could not start the PlanetPress Suite Messenger 7 on Local Computer. Review the System Event log. If this is a non-microsoft service, contact the service vendor, and refer to service-specific error code 16842771.

From the Event log:
The description for Event ID 19 from source PPMessenger7 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

I checked the licenses on the Design seat and they appear active although I have seen a few errors upon startup saying the Design license have expired, although viewing it right now it states it's activated.

Any help would be appreciated.
