[Steam] Activate Your Game Error on Launch

@TheRightDaikiro 

Do you have EA app installed?

Please provide a screenshot of the "Activate Your Game" error.

Also create a DxDiag in text file format and post it with your next reply. You can do that with the "Choose file" button at the bottom right corner of the reply window. 

Yes, I have EA App installed. I even try the reinstall option.

@TheRightDaikiro 

This is an old login that you are not supposed to see.

Please unlink and relink your Steam account here.

If that don't works, what happens if you try to start the game directly from EA app?

@holger1405

Alright, I've tried unlink and relink via the link you suggested but it did not work. It still shows the "Login form" that I am not supposed to see.

When I tried to start the game directly from EA app, it looked and worked the same way (stuck at the login form)

@TheRightDaikiro 

Please clear your temp files:

• Press the Windows key and "R" at the same time
• Into the new window, type or copy & paste:  "%temp%"   (Without the quotes.) > hit "ENTER"
• Now your Windows Explorer should have brought you to the "C:\Users\>your user name<\AppData\Local\Temp" folder. > Delete all files and folders in it.
  (If some files or folders can't be deleted, reboot and try again.)

Then:

• Go here and download "Revo Uninstaller". (The freeware version, Portable version works too.)
• Run "Revo Uninstaller" > Uninstall EA app.
• At the end of the main uninstall, Revo will ask you which cleaning method you want to use. > Select "intensive" > Browse.
• If "Remaining registration content found" is displayed > Select All > Delete > Next
• When "Remaining Data and Folders" is displayed > Select All (Make sure the "Origin Games" or "EA Games" folder is not in the list) > Delete.
• Restart the PC
• Download a new EA app setup exe from here.
• Install EA app
• Restart the PC > Test.

I tried the whole workflow and it did not help. After the last restart, I am back to the wrong Login form

@TheRightDaikiro 

Then do the same with Steam > Restart the PC > Test.

@holger1405 

I did the same for the Steam and it did not help. Still the same problem.

@TheRightDaikiro 

You disabled the compatibility mode and the other changed you made? If not please do so.

Then repair the game.

(Origin: Game Library > Right-click the game cover > Repair)
(EA app: My Collection > Click on the three dots on the game cover > Repair)
(Steam: Game Library > Right-click the game > Properties > Local Files > Verify integrity of game files.)

@holger1405 

I've done that and without all those modifications (like compatibility mode and admin mode) the form won't even appear. No error no logs, nothing at all.

It just closes the EA App, nothing, then the EA App reappears, and in the Steam Launcher I can see the "Play" button again instead of "Running".
