The application “Epic Games” can’t be opened

I’m trying to run the Epic Games Launcher to download and install UE4 on OSX, but after installing the app to my Applications folder, trying to run it only brings up the message “The application “Epic Games” can’t be opened.”

I’ve checked the log file locations and no logs are left.
The only thing I can think of that might matter is that I had an older version of the launcher that I checked out about 6 months ago, and hadn’t run it since then. I’d downloaded the latest version of the launcher from the UE website and just extracted it in there, where it didn’t run.

Hi Matariel,

Please take a look at our Launcher Troubleshooting Guide and see if any of the information there can help you. If not, please follow the instructions towards the bottom for getting your dxdiag and Launcher logs. I’ve assigned a member of our staff to look into this for you, and they’ll let you know if they need anything else.

Thanks for the reply, but as I mentioned I’m running the OS X version of Epic Game Launcher, your troubleshooting guide seems primarily focused on Windows issues, as is your mention of dxdiag.

As for Launcher logs, the app doesn’t even launch so can’t even leave a log.
I’m happy to provide OS X Console logs, if that helps.

Hi Matariel,

Feel free to post your console logs as well but could you post your System Specs?

Hi Matariel,

We haven’t heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you’re still experiencing this issue, please try the suggestion that I mentioned above. Then post back here with the requested info.



I was getting the same error after downloading the launcher and replacing an old copy of it. Rebooting my iMac fixed the issue.
