Doom 3 Won't Open After Installing Mountain Lion

[Bocuma]

I'm not sure if this goes here or not, so bear with me.

Since I purchased, downloaded, and installed Mountain Lion, everything has (so far) worked just fine. Except my digital copy of Doom 3 that I bought from gameagent.com a couple of weeks ago. It ran just fine on Snow Leopard, but now every time I try to boot it up, I get this message:

"'Doom 3' can't be opened. You should move it to the trash."

I looked online for help, and I found that turning off Gatekeeper will help. It worked for Jedi Academy (another game I bought off the same site), and all of my other games work fine as well. But Doom 3 still will not open.

Any reason for this? My guess is compatibility issues. Is there a way to fix this?

Thanks.

Is doom 3 a power PC game? ML (and Lion) removed Rosetta which was responsible for emulating power pc calls on intel systems. PPC programs won't run on Mountain Lion.

I just launched my copy of Doom 3 from the MAS and it worked fine.

Can you re-install yours?

No problems with mine launching.

Make sure you have the latest version.

Not to my knowledge. I recall seeing it on gameagents.com as having Lion support.

I've already tried reinstalling it twice. No dice.

No problems with mine launching.

Interesting. Where did you buy it from?

Make sure you have the latest version.

I'm pretty sure I do. I think it's just that Doom 3 hasn't been updated yet for ML support. It received Lion support not too long ago if I'm not mistaken.

Ah-ha! Here's the problem. Does anyone know how to fix this then?

goto settings then "security & privacy" then unlock that box to make changes then choose "anywhere" under "allow applications downloaded from:"

It doesn't work.

It doesn't work.

That's tied to Gatekeeper. Make sure Gatekeeper is letting any and all apps run despite not being signed or having a revoked Developer ID.

Although, that seems to be a generic error message not one given by OS X as a warning when launching Doom 3. It's possible the version you downloaded is not compatible with ML, does it have the App icon with a white stop symbol over it?

GateKeeper's letting in all apps, I've made sure of it. No, the app symbol for Doom 3 is normal and everything.

Alright, so I'm figuring I should just re-buy the game from the App Store. Will this work? Because to me, this whole thing looks less like a compatibility issue and more like some sort of weird DRM thing.

 

[Bocuma]

Okay, I just bought a new copy from the App Store and it works just fine. Now I know for sure that my other copy won't work because of some stupid DRM crap.

Well, that's ONE problem solved...
