PC MCC UNPLAYABLE will not launch through steam

Hello Im having some serious issues with being able to start the MCC on my pc through steam. And yes, before you ask, my pc meets the minimum requirements to run it. so anyway, as soon as the anti cheat software loads and the loading bar disappears, an error code appears on my screen. This has been happening since the game was released on Tuesday. Here is the message:

MCC-Win64-Shipping.exe - Entry Point Not Found

The procedure entry point EventSetInformation could not be located in the dynamic link library ADVAPI32.dll.

PLEASE someone help me out. Im not a pc wizard and i would really love to play reach. I’m honestly kinda pissed because i dropped my 40 bucks like a month ago to play it as soon as it came out and its been like 5 days and i haven’t been able to launch it once. If 343 doesn’t do something about this I am going to refund my purchase.EDIT: this is the first person who has encountered this issue as well that I have talked to
