This is why the internet is so amazing. Thank you. Even though your solution didn't work for me as it is, it gave me the strength to keep digging and figure out the solution for me.
The problem was that I bought the Ultimate Collection on the Origin/EA so if that's anyone else's case as well you have to install the "Fixed Ultimate Collection Launchers" by Medstar (https://www.moddb.com/games/cc-generals/downloads/new-fixed-ultimate-collection-launchers-v101). This will allow you to start the RA3 and RA3 uprising directly from the "Command and Conquer Red Alert 3\Red Alert 3\RA3.exe" and "Command and Conquer Red Alert 3\Red Alert 3 Uprising\RA3EP1.exe" exe files without launching the EA app (former Origin). Then you have to create a shortcut for the exe file and then follow the instructions from the Alqsh described above. That is right-click on the shortcut -> Properties -> and at the end of the "Target:" line copy " -win -xres 1920 -yres 1080" (including the first blank space) so it looks something like "C:\GAMES\Command and Conquer Red Alert 3\Red Alert 3 Uprising\RA3EP1.exe" -win -xres 1920 -yres 1080". Of course, you have to use the resolution of your monitor.
This will allow you to launch the game but it might be broken. The star panel might be over the game, and at the top, you will have a white line. Now close the game and delete the "-win" from the "Target:" line and lunch again. If it worked, you are welcome. Now get out there commander!
