I bought Syberia but the download with GOG Galòaxy ended with an error. So I downloaded it off line and now everything works. However, I noticed that the "game" is entirely saved in two locations: C:/GOG games and C:/program files(x86)/goggalaxy/games/Syberia
Is this normal? It occupies many KB. Can I cancel one? Which ?

1. Launch unins000.exe in that folder and uninstall it.
2. Double-check that the other copy is still installed under C:\GOG Games\.... If not, run the offline installer again and specify that path as the install location, not C:\Program Files...
3. In GOG Galaxy, click the cogwheel in the top left and choose Settings, then Installing, Updating. Set "Game installation folder" as C:\GOG Games\ if that's the parent folder of the Syberia installation.
4. In GOG Galaxy, double-check that the game is still detected as installed (you have a Play button instead of an Install button). If not, click the cogwheel in the top left, choose Add Games & Friends, then Scan Folders for GOG Games.

• Playing this game through GOG Galaxy only provides game time tracking. If you want to play it without GOG Galaxy, you should be able to use the desktop or Start Menu shortcut. If that doesn't work or it launches GOG Galaxy, you can go to the game installation folder and create your own shortcuts to the game's executable.
• Very old games try to save files in the installation folder. In modern versions of Windows, applications can't normally save files under Program Files. That's why it's usually best to install games in some other folder like C:\GOG Games.

Ok Ice_Mage thank. All right
