Unable to Launch from Steam.

Attempted to launch the game from steam. Get the error code that the game was bought from a different account. Attempted troubleshooting steps up to including:

Reinstall of both EA and Steam launcher. 
Single drive install for both launchers.
Verified files on steam.
EA cache recovery.
Ensured that EA is linked to my steam account.
Ensured both apps launched as administrator.
Accessed local file .exe file and launched as administrator.
Ensured windows defender doesn't interfere.

All attempts failed and unable to launch the game.

I recommend a removal of EA app launcher to be launched when games are purchased through steam. 
Also recommend the ability to choose the install path for the EA launcher if it is a error in the coding.
Get the hamsters working. 

I so do want to drop some expletives at every single decision maker at EA that forces the coders to ensure that their launcher is the "only choice" when it comes to games. The actions that EA also has to allow their games to be sold on steam just tells you that they lost quite a bit of money.
Recommend new training for management staff at EA.

Finally recommend re-education to EA execs. 

Hope that once BF6 launches and steam players begin having this issue, It will hit their bottom line.

Good luck!
