"opens another executable"? I have no idea what you mean with that. The Origin version starts a launcher program exactly for security reasons, since that launcher checks your Origin login. I have no idea how/why you think this is in any way a security bug or a vulnerability. It doesn't open "a random executable on your disk", it launches one specific executable on your disk. Or are they actually launching wrong games? Your explanation is really unclear.
The fix for your issue is probably disabling the Origin In Game feature, by the way, since it doesn't seem to be compatible with the C&C games. Check the sticky "How to run older Command & Conquer titles" thread at the top of the forum.
But hey, Command & Conquer 1, Red Alert 1 and Tiberian Sun are all freeware, so if you want to get rid of all that, get the freeware versions and use those. You can find them here:

Tiberian Sun:
The Origin interface launches fine. When I try to start Tiberian Sun another game - The Longest Journey, which is under Program Files/GOG Games/The Longest Journey/.... launches. That's not an origin game, it's not installed via Origin, its not showing up in the Origin interface. That is what I mean by random executable on my computer. Another application that has nothing to do with origin or tiberian sun is launched.
Same problem here.
When starting Tiberian Sun, the The Longest Journey-launcher (GOG) pops up instead. It indeed being installed in a different folder then TS; TS is installed in Origin\Games\..., TLJ in GOG\Games\... On the same HDD, btw. Went to the installation folder and tried to start the game via the Game.exe, Sun.exe and TSLauncher; same thing there, naturally.
First I thought that may have been because, if you want TLJ to run properly you had to add the Game.exe to the CCC (Catalyst Control Center), incase you have an AMD-card. But removing that didn't change anything either. And, no, the TLJ.executable doesn't start Tiberian Sun all of a sudden, I checked. 😉
Now the easy solution is of course to uninstall TLJ, and that works like a charm. But because TLJ is one of my favorite games, that's not really a ideal option. Is there a way to change the command-line, or something?
The install paths on our computers seem different - so probably the Origin app does some registry lookup and ends up getting the Longest Journey executable instead. Since this is reproducible its probably not a random thing and someone did some sloppy coding somewhere. I don't think anyone will make a patch for this, ever.
My solution was to uninstall TLJ and stop playing C&C Tiberian Sun after realizing it is indeed 2015 and nostalgia doesn't solve anything. Another possible solution - if TLJ is truly one of your favourite games - is to show some integrity and buy a computer specifically to play it.
Good luck!
I just don't have them installed on C:\.
And I've figured it out. The problem is that both games have the executable Game.exe. No other games I have, have that. So I changed the TLJ executable from game.exe to games.exe. So when I now start Tiberian Sun, it launches normally. Same still goes for TLJ. It's thankfully that simple.
And there's nothing wrong with nostalgia, btw. 😎
