EA app games won't open, says it needs Origin

@Shopaholic74  Try running the EA App as an admin: right-click on the shortcut and select "Run as administrator."  And make sure your games are NOT set to run as admin.  You can see this by right-clicking the shortcuts or the original .exe files (TS3.exe, TS4_x64.exe, TSM.exe) and selecting Properties > Compatibility.  There's a box to check to run an app as admin; make sure it's unchecked for these.

If this doesn't help, please let me know what antivirus you use.

So I just did that, and now it does go to open the game, but then gives me the alert that the game is already running, which it is not (I do share the account with my mom, so it would be understandable if I cannot play Sims 4 while she also is, but she doesn't play 3 or Medieval, so I know that's not the cause for it)

@Shopaholic74  What antivirus do you use?  If you're not sure, you can check the Task Manager, including the background processes list, for anything that looks like it belongs to an antivirus.

I use Mcafee 

@Shopaholic74  Try setting exceptions in McAfee for TS4_x64.exe and EADesktop.exe.

I just did that, and it did not work, it still says that the game (any game I try to open) is already running.

@Shopaholic74  Try creating a new admin Windows account and playing in that.  Make it a local account, as in, don't sign into Microsoft, and don't sync with any other services you normally use.  You'll be able to sign into the EA App and launch your games, but your save data, for Sims 4 at least, won't be available.  That can be addressed later, but this is just for testing.  Let me know whether it works and we can go from there.

@Shopaholic74  Please try disabling McAfee entirely, at least long enough to test Sims 4 and one other game.

If that doesn't help, please run a dxdiag and attach it to a post.

Disabling McAfee didn't work, so here is the dxdiag report thing.
