Hey guys!

Thank you in advance!

Hi s4Ndw1ch,

I’m sorry that you are having an issue with the Epic Games Launcher. In order for us to offer the best support, we have recently modified the process for how Epic Games can help troubleshoot your Launcher issue. Please visit for technical support, here you can find information and solutions for common issues, as well as a contact form if you still need additional assistance. To access the contact form, please use the “Email Us” button under the “Contact Us” section. Thanks!

This error is caused by the Microsoft UAC (User Account Control) prompt requesting access while installing a product through the Epic Games launcher. If you ignore, don’t see, or deny this request, the install will cancel and result in this error. You should be able to solve the issue by Resuming/Repairing the associated product installation and clicking “Yes” when prompted by the UAC.

And yes, it’s completely ridiculous that it wasn’t coded to wait for your response.

Basically run the Launcher as Administrator :wink:

Problem fixed!

Right-click on your Epic Games launcher desktop shortcut Select “Properties” In the line labeled “Target,” add the following to the very end (after the quotation mark): -SkipBuildPatchPrereq It should look something like this: “C:\Program Files\Epic Games\Launcher\Portal\Binaries\Win64\EpicGamesLauncher.exe” -SkipBuildPatchPrereq

Click “Apply” Double click the shortcut to run the launcher and try again and make sure to add the space between the quotation and dash

thanks a lot!! it worked!
