NDT Server EXE Version?

Trying to run NDT Version 2.00 Sp2 as a server, but keep getting the diference between server and client error.

Documentation says to use 4.00 or greater.

Have tried server exe’s (Full file sets) from 3.70 to 4.02 same message everytime “database error 1111. The client and server do not have the same program version number”

Current Server.Exe is Build No. 21544 Product Version

Anyone have any ideas?

Same Database works fine as a local NDT DB.
