Issues with OpManager 12200 Enterprise install

Issues with OpManager 12200 Enterprise install

Good Evening
      We have installed OpManager 12200 Enterprise from new. (New Application server and new SQL Server)

I have managed to get the system to install but the windows service does not start. 

It errors with the below error messages:

Event Logs - "The ManageEngine OpManager Central service terminated with the following service-specific error: %%4294967295"

Service Start - Attached

Can you please assist with this as we are unable to get the service started.

Many thanks
