Nemesis Failed to generate Behavior

[Kgn001]

Hi, 

I'm trying to go through the STEP SkyrimSE v2.3 guide. I am at 19-Utilites and trying to complete the step for Nemesis. So far everything has been going well but when I run Nemesis, and check Ice Skating Fixed for Real, then Launch Nemesis Behavior Engine, I get the following output:

Initializing behavior generation

Mod Checked 1: nemesis
Mod Checked 2: isffr

ERROR(6002): An exception has occured while patching. Report to Nemesis' author immediately

Failed to generate behavior

I have tried adding Windows Defender exceptions for MO, Nemesis, etc. I turned off Real Time Protection, I have restarted my computer, and nothing is working. 

I'd really appreciate some help.

I have managed to resolve this issue.

I completely removed Nemesis, re-added it, set its .exe to run in compatibility mode for windows 8, and made sure I was running MO2 as admin.
