Which Patch 1.7 for Eurogamer's GetGames download version?

[AJ888]

Just purchased the game from Eurogamer's GetGame.
The version is: 1.6.4
Build: 34.387

So which patch should be used to update it to version 1.7? or at least 1.6.5?

I tried both the GamersGate patch version and the 1C publishing version. On both patch attempts, the update completes successfully, but starting the game now requests a CD/DVD. Luckily I could reinstall the game and go back to version 1.6.4, but many gameplay issues were resolved in version 1.6.5, so I'd at least like to get it to that version...

Any help would be appreciated!
