As the title says.
I can't save the game.
Uninstalled and installed it, still got the problem.
Change it to always run as admin, still can't save.
Anyone have any ideas what the problem is?

the default folder for saves is in your
C:\Users\USERNAME\Documents\My Games\Star Ruler 2\saves
folder... I would assume you installed to c\programs folder or you have a bad antivirus software

what system is it i.e, window 8, 7, 10?

1. the saves folder should be read only... thats a windows 10 thing
2. Avast = start your game and goto the community tab... if you get online then the firewall is playing nice.

Q what install path did you use for the game example mine = C:\GOG Games\Star Ruler 2\Star Ruler 2.exe
Q this game is English only so Control Panel\All Control Panel Items\Language = at least one english?

2. Avast = check, I can access Community tab at Galaxy, Layout (Shift + Tab) at game, and at the first in game screen I see Wake of Heralds Expansion and V2.0.0 Update News.

3. I'm using F:\GOG Games\Star Ruler 2\Star Ruler 2.exe. But will install at C drive to see if something happens.
Edit: Change the drive. Still cannot save.

4. I have Portuguese - Brazil enabled as my primary language and English - US as my secondary language.

Edit 2: I tried to contact the developers through Twitter. Also tried to create an account within the official forum. But no reply to my twit and the forum won't allow me to create an account.

Test 1: Avast was the problem. Without Avast I can save now. Go figures.

Thank you for all the help :D

Also did test 2, but since it was after uninstalling Avast it also worked.

FWIW, AVG does the same thing since the Thursday update. Specifically, it is being cause by the Ransomware Protection service which was introduced on (you guessed it) Thursday.

To fix the problem in AVG under Windows 8, open the AVG console, click Menu, select Ransomware Protection, then Blocked/Allowed Apps.

Now click on Allow An App and navigate your way to the Star Ruler 2 folder (probably C:\GOG Games\Star Ruler 2). Find the folder called "bin" and open it. Open the folder for your OS (e.g. win64 for Windows 8). then click ONCE on Star Ruler 2.exe and then click on the Open button.

You should now be back in the Ransomware Protection, Blocked/Allowed Apps menu with Star Ruler 2.exe showing as an allowed app.

I hope this helps any lost AVG users who find their way here.

I encountered the same problem. For a personal reason, It was mandatory that i didn't uninstall Avast, so I had to go around it. The way i managed to do so was by going into Avast program, settings tab, components tab, and disable the Ransomware Shield. You can do that while the game is running; just use the windows button on your keyboard, disable the Ransomware Shield, go back to game, save; after saving feel free to unable the Ransomware Shield back on again. Repeat as needed.
