Ask your question here if you can’t find the answer in the FAQ.

Winner, I suggest adding information from the forum to the FAQ. Yesterday, I helped a friend, and this was the only thing that helped. It fixes the error with the launcher without reinstalling the system. :smile20:

Disable antivirus programs, firewalls, and the Windows firewall.

Open the Control Panel - Programs and Features, and uninstall Ubisoft Game Launcher.

Try installing the updated UbisoftGameLauncherInstaller.exe client.

Open the hosts file (C:\WINDOWS\system32\drivers\etc\hosts).
If you had a pirated version of the game installed, the following lines will be in the hosts file:

127.0.0.1 static3.cdn.ubi.com
127.0.0.1 ubisoft-orbit.s3.amazonaws.com
127.0.0.1 onlineconfigservice.ubi.com
127.0.0.1 orbitservice.ubi.com
127.0.0.1 ubisoft-orbit-savegames.s3.amazonaws.com

Delete everything except:
127.0.0.1 localhost

If you have the Nod32 antivirus installed, completely uninstalling it may help.
