Factorio Forums

When I try to load the game from Steam, I get an error message: "Error in assignID, item-subgroup with name 'fill-barrel' does not exist." I tried deleting my mods from the appdata folder. Still got the error message. I tried uninstalling the game from Steam, reinstalling, now I get a different error message: "An error occurred while updating Factorio (missing file privileges) : C:\Program Files (x86)\Steam\steamapps\downloading\427520\bin\x64\factorio.exe" What is going on?

Your game downgraded from 0.15 to 0.14 (Steam probably forgot you opted into 0.15 beta), you have to delete Factorio\data\base\data-updates.lua to make 0.14 work after downgrade.

As for error on Steam, it seems to me as some kind of issue with filesystem on your computer. Maybe failing hard drive, maybe just one time hiccup. Try to manually delete folder "C:\Program Files (x86)\Steam\steamapps\downloading\427520"

Ok, I'll try deleting that download folder

Tried, Windows said that I need permission to delete that folder. Require permission from dezeeuw2W10\dezeeuw2 to make changes to this folder. Not understanding that, I'm the only user on my laptop.

Ended up just uninstalling Steam all together. Reinstalled Steam and Factorio, working fine.
