How to launch the game without updating?

I have not updated the game but can't figure out how to get the current version to run without trying to update. I have my Steam .acf file set to read-only, so Steam can't update it, but no matter how I try to launch it keeps trying. Even running the executable directly or trying to launch with SMM. Is there any way to get it to run the version I already have without updating?
Solution:
So, to create a single post to mark as the answer for this issue: For Epic: 1. Make a copy of the game folder wherever you want it. This must be from before the update....

Having a similar issue. Apparently the announcement has brief but incomplete instructions on backing up your game files to be able to play modded game but no real follow up for after the backup part

Yeah, I know the normal trick for Steam where you bakup the current game files, let it update, then replace the files with your old version, but that is not working here. Everything I have tried fails and no matter how I try to launch the game it always crashes out because Steam is trying to update.

In on Epic having the same thing. SMM and the direct application EXE will not launch and will bring up the epic games launcher without the game. Seriously it’s 2024 how do we not have basic modding support in the launchers for early access games?

I’m just hoping by shamelessly bumping your thread to get someone knowledgeable to reply . Meanwhile I’m stuck with a broken back and both the games I want to play (SF modded and Warframe) are having issues I can’t resolve without expert help

What I don't get is why launching the executable directly doesn't work when that works for almost every other game out there. It's like Coffee Stain intentionally made it so you can't play the old version. I know they don't want official mod support, but come on! lol

lmao I'm starting to think it may just not be possible. I see other, much newer, threads getting quick responses, but crickets in here. Maybe because nobody knows how to get it to work?

Will do. Post is live on Reddit in the largest Satisfactory subreddit.

Running old version is pretty simple. Step 1: You need a full game copy from update 8. If you already updated, you have a problem. Step 2: Create a shortcut to the game exe. In target field add space and -epicportal. This disables the epic/steam integration. Step 3: Run the game from new shortcut. You will load offline, most likely spawn as new player. Thats normal.

Works fine for me, even spawned in my original body:

Unfortunately, that does not appear to work. -I have a copy of the U8 version of the game that has not been updated. -I created the shortcut exactly as shown, with "-epicportal" added at the end of the Target field. Even with Steam completely closed, the game starts to load but then closes back out, Steam automatically runs and tries to update.
