Hello
The 1.01 to 1.10 patch is no longer available for download. I can only apologize for the inconvenience and advise you to download the updated installer for the game (setup_the_witcher_3_wild_hunt_2.0.0.52), it is in the current version (1.31) and does not require further updates. The offline installers for the DLCs are also updated to the current version. After downloading all these installers can be stored for future use.
You have three download options for the offline installers:
1) Downloading the installation files with Galaxy. Installation files use a different delivery method, and are usually smaller than the files downloaded during "installation". To do this, find the game in your Library in GOG Galaxy, and click MORE > Backups & goodies, then click the appropriate Game Installer,
2) Using the GOG Downloader. You can find it here:
https://www.gog.com/downloader . Once downloaded and installed, please find your game on gog.com in your library, and click MORE > GOG DOWNLOADER LINKS,
3) Downloading with your browser - this isn't very recommended, as it offers no pausing/resuming, and no error protection.
Regards
