Update issues


Not getting Patch 8

For OSX the update is not quite ready. It should be available soon, but we do not have a specific ETA yet.


For Windows:

What is the version number shown in the bottom left of the launcher (under the Play button), or bottom centre of the main menu in-game? The current patch 8 version is 4.1.1.1695932.
If you were expecting the version number to correspond directly to the patch number, the initial 4 is actually the generation of the game engine (D:OS 2 version numbers started with 3.0 for the original release, for example, and 3.6 for the Definitive Edition).

To get the latest version (see the pre-patch announcement for details):
In the Steam library, right click on the game and select Properties, switch to the Beta section and then in the dropdown list select 'None'.
With the GOG release, in Galaxy select the game, then the settings icon at the top right (beside the Play button) and under Manage Installation select 'Configure...'; after that either check automatic updates or select the latest update in the list of available versions.


If that wasn't the issue, try logging out of Steam/Galaxy, exit the client, reboot, start the client again, log in, and see if that helps.

Try verifying local files: in the Steam library, right click on the game and select Properties, switch to the Local Files tab and then click on the 'Verify Integrity of Game Files...' button.
With the GOG version, in the (optional) Galaxy client, select the game, then the settings icon at the top right (beside the Play button) and under Manage Installation select 'Verify / Repair'.




After the latest update, previous saves can not be loaded

Is there a 'Deprecated version' error in the load window? (on the bottom right, where it shows the save version number)
Unfortunately, due to the nature of changes in major game updates during Early Access, it is not possible to maintain backwards save compatibility. Saves from patch 7 or earlier (up to 4.1.1.1524131) will not work in patch 8 (4.1.1.1695932 or later). However, you can revert to the earlier game version to be able to continue with your existing saves (see the pre-patch announcement for details).

In the Steam library, right click on the game and select Properties, switch to the Beta tab and then in the dropdown list select Patch 7.
With the GOG release, in Galaxy select the game, then the settings icon at the top right (beside the Play button) and under Manage Installation select 'Configure...'; after that uncheck automatic updates, if required, and select the last version before the patch 8 update (4.1.1.1524131).
Currently Stadia does not support delaying an update (as can be done with the GOG version) or beta branches to keep the older patch versions available (as on Steam).




Problems with the install process itself

Try logging out of Steam, or Galaxy for the GOG version, exit the client, reboot, start the client again, log in, and see if that helps.

If possible, try verifying local files: in the Steam library, right click on the game and select Properties, switch to the Local Files tab and then click on the 'Verify Integrity of Game Files...' button.
With the GOG version, in the (optional) Galaxy client, select the game, then the settings icon at the top right (beside the Play button) and under Manage Installation select 'Verify / Repair'.

With the Steam version:

In the client, in the Steam menu select Settings, then Downloads, and try changing your Download Region.

Try exiting out of Steam and check the SteamApps folder where the game is installed, and if there is a file there called appmanifest_1086940.acf.tmp.save, delete it and restart Steam. Issues with that file can cause problems with the update or install process (such as Steam repeatedly pausing the download).

Try clearing the download cache and reboot your computer (in Steam, Settings, Downloads section).


Try checking your drive(s) for errors. In Windows Explorer, right click each drive and select Properties, switch to the Tools tab and click Check Now in the Error-checking section. For the boot drive this will prompt to schedule a scan for the next time the system is rebooted.

Make sure you have enough free drive space to install the update/game (twice the download size, plus enough for the update/install process). With Steam for patch 7 to patch 8 the download is about 37GB, with the total free space needed for the download and update about 104GB; with the GOG version, with Galaxy the download size is slightly over 86GB.
If required, a program such as WizTree could help track down files and folders taking up the most space, some of which you may be able to delete or move to a different drive, etc.


If nothing else helps, you should at least be able to uninstall the game, and try a clean install (before deleting, right click the game in the Steam library, select Properties, switch to Local Files and select 'Browse Local Files...', then after uninstalling the game, make sure that folder is removed or empty).

You could also try reinstalling Steam. You can effectively do this without having to redownload any games installed on the same drive by deleting everything in the Steam install folder except for Steam.exe and the SteamApps folder, rebooting and running the Steam.exe executable.
