Alright. Find where your game is installed and let me know.

hardrive

Haha, I know. I meant if you had multiple drives, or if it's in C: drive, etc.

its in D

Ok, because we're gonna come back to that in a bit. First thing you need to do is uninstall all mods, including configs, plates, all that. Go unsub from all of them.

already did

Good deal. Next, make a folder on your desktop. Name it 'CMS 2021 profile backups' or whatever you prefer, then go here: C:\Users\(whatever your user name is)\AppData\LocalLow\Red Dot Games\Car Mechanic Simulator 2021\Save

Copy and paste the profiles in this folder into that desktop folder you created, because uninstalling the game will erase your profiles.

so is a file or do i need to use the run tool

Just a file to copy/paste from one folder to the other. If you have multiple profiles you want to keep, copy/paste them all into the desktop folder.

would it be called
profile0.cms21
profile1.cms21
profile2.cms21
i have 3 saves

Yep, those are the ones. ;)

Copy/paste those into your desktop folder you made.

do i need to zip them or anything if not im done with that

Nope, all good. Double check your desktop folder and make sure they're in there.

If that's all good, and they are in that folder, uninstall the game through steam.
