EpicWebHelper.exe has encountered a serious problem and needs to close.

Hello,

I've installed the Epic Games Store using Crossover, however when I open it, I get the following error:

"The program EpicWebHelper.exe has encountered a serious problem and needs to close."

I hit close to close the window, and it keeps reappearing and the Epic Games Store never opens.

There was an issue when I first installed the app, when it gets to installing the Epic Games Store, it opens the installer, runs the update, then says "Initialising Prerequisites" or something like that, and it just gets stuck there (left it for an hour with my MacBook fan going like anything the whole time). I force closed it, and now I'm at the error that I explain above.

Here's the additional details from the "EpicWebHelper.exe has encountered a serious problem and needs to close." message:

Any ideas? Cheers

I am having a similar problem...

The Epic client is known not to work that’s why things like Legendary exist.

I am also experiencing this issue. And as far as I know, legendary does not exist for Mac. I have attempted to use legendary on Linux and it only works with the default wine prefix and offers no tools for configuring the games it downloads.

Legendary use make use of env WINEPREFIX for setting the none default prefix. They provide a Windows .exe that should run via wine on macOS.

I’d need to do some digging in my discord history but someone did link me a forked version of some GUI that’s used Legendary and indeed functions on macOS.

Awesome, thanks for your response, I've never heard of Legendary. If you're able to find the link to the forked version that you mention, that'd be greatly appreciated.

Check this fork of HeroicGamesLauncher on the releases section there's a prebuilt binary that should function on macOS Mojave and later. This wasn't tested using CrossOver wine* binaries however.
