In-game window reading "Save failed". Can happen when saving changes to settings or at bases during game-play.

There are a couple issues than can cause this. Either Just Cause lacks permission to write and modify files or an anti-virus program is blocking Just Cause from making changes to your computer.

First check your antivirus software to see if it's blocking Just Cause from modifying files. If you don't have third party antivirus software installed, check Windows Security to see if its ransomware protection has blocked Just Cause. To check, open Windows Security and go to Virus and threat protection -> Manage ransomware protection -> Allow an app through Controlled folder access -> Add an allowed app -> Recently blocked apps, and add JustCause.exe to your allowed apps, if it's listed. You can also add JustCause.exe by going to Browse all apps and finding it with File Explorer.

If your antivirus software isn't blocking Just Cause then set JustCause.exe to run as an administrator. To do this, open your installation of Just Cause, usually found at and right click JustCause.exe. Go to Properties -> Compatibility and enable "Run this program as an administrator". This should allow Just Cause to write the files necessary for saving.

This happens when Just Cause can't locate the Steam.dll file. This may occur if Just Cause and Steam are installed on two different drives. I experienced this issue after setting JustCause.exe to run as an administrator while trying to fix another problem.

Copy, don't cut, the Steam.dll file from your Steam installation, usually found at and paste into the Just Cause installation, usually found at
