Error after restoring to new server

Hi,

I am attempting to restore to a new application server and a new SQL server. I got as far as installing the application on the new server and database (confirmed it worked), restored the data with restoredata.bat, which succeeded, but now the service fails to start with Event ID 7024 in the Windows System Log:

Event ID 7024:

The ManageEngine ServiceDesk Plus service terminated with the following service-specific error: Incorrect function.

Some things have changed between the servers.

Old servers were on 2008 R2 and SQL 2008. New servers are on 2012 R2 and SQL 2012.
Installation on the old server was on the D: drive, installation on the new server is on the C: drive.

I spent time looking through the forums and configuration files trying to figure it out but am at a loss. Anyone have any ideas?

Thanks,

-Mark
