id like to have 2 instances of factorio

[sullen sluice]

id like to have a 1.1 and 2.0 version. I have an old 1.1 modded save going through steam which id like to finish.
However when i downloaded a spaceage version from the factorio website, it opens and shares all my save files and mods and stuff, and i dont want to disable all the mods, because then i might miss some when i need to re-enable them for my 1.1 modded save. any advice as to how i can fix this issue?

The save files themselves record their version and mod configuration. When you open a save that has different mods than what you currently have enabled, a prompt will open asking if you would like to switch your mods to match the save

If you are frequently switching between 1.1 and 2.0 this might mean you have to reload the game frequently, but you shouldnt be able to open a save from the wrong version without the game giving you a warning

If you want to complete your 1.1 Map, in 1.1, you would need a separate installation.
You can download the installer from the Factorio Site: https://factorio.com/download/archive/1.1.110

Then you can keep your 2.0 Save/Mods running on Steam, while your 1.1 Save/Mods are on a separate program

i downloaded a 2.0 version from the website already, and have my steam version kept at 1.1

the problem is, i want to use some of the mods in both versions, a 1.1 version of the mod for my 1.1 save, and a 2.0 version for the different save, and if i update the mod i cant then redownload an older version of the mod

[midnight quiver]

That is a fault of the mod developers. They need to set the valid version range to be >1.1 & <2.0

You can also download manually from the mod portal website

ok so there isnt a way for me to have 2 seperate versions of factorio then?

Did you download the standalone zipped version from the website?

It should be completely separate from a steam install.

Then you can copy the steam save file over to the standalone directory

I have Steam updated to 2.0, and I downloaded the Standalone Zip from the Factorio website to run 1.1. I just needed to copy over my game saves and BPs from the default folders to the standalone's folders

[stone oyster]

yep, exactly what im doing in order to maintain a SE playthrough

You can have separate mod folders with a 1.1 game shortcut pointing to the 1.1 mod folder and a 2.0 game shortcut pointing to the 2.0 mod folder: https://www.reddit.com/r/factorio/comments/112e235/comment/j8jw8ru/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button. Mod folders don't even have to be in the game install directory. I made new folders in an external drive and copied over existing mod zip files, mod-list.json, and mod-settings.dat from the default folder.

[sullen sluice]

yeah i did

wait so i need my steam to be 2.0, and the website download version to be 1.1, not the otherway around

and then it just works?

You can do either one. I did Steam for the 2.0 vanilla achievements and standalone 1.1 for my legacy modded maps
