Bug corrupted file

What can I do to fix this and is there a way to fix this without redownloading the launcher and all the engine versions?

When I launch the launcher I get this error:

I’m sorry that you are having an issue with the Epic Games Launcher. In order for us to offer the best support and help troubleshoot this 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. Thanks!

Can’t I just post it in the forum?

I’m sorry but this forum is for community discussion about the Unreal Engine. Official support is not provided here in any format (forums are too chaotic and impossible to track), but additionally the Launcher is an entirely separate product from the Engine. Our Launcher support team does not operate here.

Here is the direct contact form (from the link above) in order to get assistance from Epic:


I didn’t know that.

Thanks for telling me.
