[PC] Mass Effect 3 Won't Launch

@Chekkonen86 

Glad to hear you had success.

Yes, Origin will open on it's own, and let me log into Origin, where I only have 2 games:

Mass Effect 2 Deluxe Edition and

Mass Effect 3 N7 Digital Deluxe Edition.

However, when I used to play the game, I would only click on the shortcut icon, which then would pop up a steam notification, then have Origin open and close, then start the game. I appreciate you still taking the time to help with me, and everyone else that has problems with this. I have a few other questions about trying to start the game. I have read through previous forums that have other solutions, one of which regarding "Compatibility Mode" under the "Properties" section for ME3. I have read that some people have solved this not launching problem by fixing the compatibility mode to Windows 7 or 8. Some have even said it works with Windows XP (Service Pack numbers I can't remember). I have noticed when I have tried changing that, Origin then would do something weird after installing. It would do a search for an update, and then give an error message saying it couldn't connect to the internet, which I cannot figure out how. So obviously that didn't work for me, or I may have done something wrong, I would still appreciate any additional support you can provide. I have also read that some people did a complete reinstall of Windows 10, clean boot, reinstall systems. I am not 100% certain this would work because some have posted that the reinstall didn't completely solve the problem, and especially since it's only one game that stopped working. Again, I would still appreciate any other ideas or solutions, anything. Thanks.

But is ME2 working?

Do you have ME2 exclusive in Origin?

A test in compatibility mode can't hurt, but I doubt it will solve this problem.

A clean boot also can't hurt. But disable afterburner or similar software (if you use it) and your antivirus software in clean boot mode as well.

A fresh installation of Windows might work, but I can't guarantee it, there is simply no real indicator what the problem might be.

I would start with a repair installation anyway .

No I have all three games (Mass Effect 1,2,3) on Steam. Mass Effect 2 would always launch via Steam, not Origin. I have not downloaded ME2 from Origin, it would run normally. I have "only" needed to install Origin when I started up Mass Effect 3. The only technical problem I had when I first launched ME3 was a Nvidia Pshyx error, which was solved instantly with a repair option from the control panel. I will try reinstalling Mass Effect 3 and Origin, and see if I have any progress with the previous solutions. I will reach out if I have had any success, or more problems.

My game finally works! So after reinstalling Origins and ME3, I tried turning off compatibility mode to see if that would work. It did not, caused same issues (Steam refreshing, Origin opening and closing), and still the game wouldn't launch, However, I searched for the MassEffect3.exe app under the Binaries folder, ran that as admin, and the game actually launched! Since I didn't have both Mass Effect 1 and 2 reinstalled, I knew I would have to start a new game. Strangely enough, I found my 2 characters Save Files that carried from ME2 (Male, which I finished already and Female, which I didn't.) I did notice however that I was getting achievements (again) as if I never got them to begin with, but Steam obviously has everything I collected from the first gameplay through. I managed to play the game through the first 2 priority missions, up to the point to check if ALL the DLC was installed correctly, and so far they are (clothing, weapons, mission for Prothean squadmate). I am hoping this is a permanent fix, seeing as I actually got the game to work, I just can't launch from Steam or from Origin, even though the .exe launcher is from the steamapps folder. Anyway I just wanted to say thank you so much for your technical advice and suggestions, and of course, patience. I know this game is pretty old, but I have enjoyed this series since I first touched it on PC. I am also appreciative of you taking the time to help me and others find solutions for this.

@DeathXMetal92 

That is good to hear. 🙂

I still will mark post #13 as the solution, as it is most likely to solve the problem regarding the Steam/Origin interaction.

Have fun gaming!
