This patch is NOT necessary to install the Enhanced Edition. Patch 1.35 can be used as a more lightweight (118 MB) alternative to the 11 GB Enhanced Edition (3.0) patch for the owners of retail copies of the release (1.0) version of The Witcher 2, which requires patching to run.
To patch your vanilla The Witcher 2 installation to Enhanced Edition manually, use the links below. More info on patching below the links.
PLEASE NOTE! This patch is not for Steam. If you use it you will render the game incompatible with Steam. The current Steam version of the game is already 3.4 (the latest version) from the very moment of installation.
Also, note that this patch is NOT FOR ENHANCED EDITION, as it already is on this patch’s level (3.0). This patch upgrades the 2011 release version of the game to Enhanced Edition.
The game will automatically update to version 3.1 via the game launcher. In case of any problems with the automatic patching system, please download the file manually by clicking the button below. PLEASE NOTE! If you have an older version of The Witcher 2 you need to update it to Enhanced Edition before using the patch 3.1.
