ERROR: Forbidden windows kernel modification detected

[Ragir 4,740]

This error is mostly related to Insider Preview versions of Windows. EAC is adding support for those version as they come in, but it will always take at least a few days for them to implement, push update to us, and us to patch it into the game. There's no way around that other than what EAC suggests:

The easiest way to avoid these errors is to opt-out of the Windows Insider Program and revert to the previous Windows version outside of it.
