As 3ti65 mentioned in his post at: https://bf3reality.com/threads/redeeming-and-installing-vu-rm.9/
I go through all the steps. Unfortunately after redeeming the key i’ve noticed there was no Link to the origin account made.
Maybe @kiwidog, @NoFaTe, can have a look. Sorry to poke you and to begin with an error like this.
You link your Origin account in-game. Download and launch VU, login, and it should prompt you to link your Origin account. If you already have Origin running in the background it’ll do it for you automatically, so if you see the soldier creation page you’re good to go.
