The Witcher 1.5 Patch focuses mainly on removing the troublesome DRM (Digital Rights Management), allowing you to play the game without the disc, while providing many additional hours of fun thanks to five new adventures created by the fan community.

Note: Unlike previous patches, this patch is not cumulative and assumes that you are patching a 1.4 version of the game.

The Witcher Patch is the next stage of The Witcher's life, and is also a means of expressing our thanks to the modding community for their hard work ion creating the adventures. The update is also be in the The Witcher: Enhanced Edition Director's Cut which was released on July 31, 2009.

Patch 1.5 features


  • copy protection (DRM) has been removed (see How to remove TAGES from your system), which means that playing the game no longer requires the game disc in the drive
  • previously introduced problems with EAX and blur resolved
    • EAX technology did not operate properly in conjunction with the game, generating critical errors when activated in the Game Options panel
    • eliminates the blur (deriving from “glow” effect augmentation) remaining after cut scenes and dialogue sequences

Additionally, there are five new adventures made by the Witcher community:

The new community adventures are available in English only (for the time being)! In order to install patch 1.5 correctly, you should have original Witcher game upgraded to 1.4 (enhanced edition). It can be found here

File integrity

To check the integrity of downloaded files, one can use an MD5 hash to calculate the MD5sum of the downloaded file and compare it with a known good sum. Below is a table of known good MD5sums (the list will be fleshed out shortly):

Filename MD5sum
TheWitcherPatch.1.5.exe 30EF893614F62DD712B3855F6D0FA663

There are many tools that can calculate an MD5sum, for reference one can use the freely available MD5-Checksum by Nero because it lets you specify a known good MD5sum and it automatically compares it with the MD5sum calculated from your chosen file.

Verification process

Step 0. Copy a MD5sum into the clipboard by selecting a MD5sum from above for the wanted file, and pressing CTRL-C.
Step 1. Start the MD5-Checksum program and press PASTE, the sum will be written in the program.

Step 3. After you choose the file the program will calculate the MD5sum, be patient, this can take a bit depending on the speed of your hard drive and processor.

MD5sum correct
Step 4. If the MD5sum is the same you will get a message saying "MD5 Verification succeed!".

Step 5. After pressing OK the MD5sum will be shown in a green color, now you can paste another MD5sum and check another file.

Step 6. If the MD5sum is not the same as the correct one, or if you accidentally modified the written MD5sum an error message will appear stating "MD5 Verification Failed!" and some directions are given, if this happens to you then it means that the file needs to be downloaded again.
