are you running Nemesis as admin? is this error consistent 100% all the time?

[nahmercy]

Ran into the same problem. I also ran the engine in admin mode and nothing changes. However, this occurs when I ran it from MO2. When I ran it outside of MO2 with no mods, the patching works. Here's my logs:

Sorry for the late comment was out of town. I can run it as admin but it will not have any of my mods so it will work fine. it seems to only happen from running it as a executable in mo2. I have to redo my mods anyway so if it comes up again after ill post again.

No no, different issue. The message is obviously different

I have received reports latest version of MO2 is causing some issues. My testers have confirmed to me that reverting back to older version fixes their issue. I'm not sure if its related but do give that a try as well

Got the same problem, first time using Nemesis and it's not going too great lmao.

Not sure what to do here. I can't run it in admin from MO, and running it manually mean there will be no mods to tick.

Edit: Found the problem. I manually installed Nemesis by dragging and dropping into my data folder, and then tried to open it using MO's functionality. You have to commit one way or the other. If your game is managed by MO, use MO to manage Nemesis as well as using it to launch it. Might fix any issues for those who are having the same problem.

[GlCap]

Same error using MO2, installed with MO, Skyrim SE version

Same issue.. it seems random it varies between error 6002 and 6001

[bluesquares01]

The problem I had with mine was my anti virus, I had to turn off my real time protection and then it worked I don't know if the same would work for any of you.

[VeganFire]

Thanks, bluesquares01. That actually worked, but it's far from ideal that we need to turn off our antivirus to get Nemesis to run properly.

[FabioFusimoto]

If disabling the Antivirus is too extreme, you can exclude the folder Nemesis runs at from the real time protection. Doing so for Windows Defender solved my problem. You can follow Microsoft's guide to replicate said exclusion

[Dcaster10]

I have been getting this error as well. Was working fine for me the other day. Now I am getting this message all the time

I tried disabling the anti-virus protection but that didn't work. Hoping someone can offer any other suggestions.

edit: tried again and getting a different message, same error code

Friend, it really worked thank you)

[FabioFusimoto]

@Dcaster10 As far as I know, ...\AppData\... is a Windows protected directory (just like ...\ProgramFiles\...), which is known to cause issues with mods. I'd highly advised against installing Skyrim on system protected folders, because unexpected stuff happens (and your case might be an example).

Recently tried to update a mod list with TUDM and when I run I get a few variations on the same error message.

Just ticked NEMISIS PCEU after disabling it and I don't get this error message hope this helps.

[Marcos3g]

I had the problem and turned off real-time protection and it worked.

[Pedaltothemetal]

IDK why but a comment previously posted also works, without disabling my antivirus nor adding folder exceptions (idk how in windows 11). I turned the compatibility mode in the executable for nemesis to "windows 7" and now It Just Works™

[vanpunch]

I also had this problem, setting Nemesis to run in 'Windows 7" compatibility mode worked for me.

[arluke]

Can also confirm running this as Windows 8 Compatibility worked for me to solve this issue. Currently on Windows 10 build 21H2 managing and running through MO2 v2.4.4.

[343GuiltySpark-04]

ok, I feel I should note that it did fix it for me however you should never turn off real-time protection globally, instead you should add an exclusion.

I only have this happen when I have my VPN on. I turned it off and problem went away.

[silmshady1984]
