So I'm not sure what exactly you wish to know.
Logging into the Game is not interchangeable, you have to use steam to log into a game account bought from steam. Logging into a game account bought from VR has to be done with the VR launcher. VR wanted to get them linked, but it turns out to have more tech difficulties than they expected.
Can you be more exact about what is happening that you don't expect?
There was no new one released for EA.
The current launcher is v.184
