I tried running the patch and I got:

"This patch does not support your version of the game
please download a new installer"

My version is the original + the 1.01 patch.

Are you kidding?

It sounds like patch 1.02 requires patch 1.01.1. If you didn't install patch 1.01.1, you skipped a patch, which means that you will need to re-download and install the full install version of 1.02. This is standard procedure, and unfortunately it's also standard procedure for GOG to go way out of their way to intentionally make it extremely difficult for us to know when an offline patch has been released. It's all part of their motto, "Use Galaxy so you won't miss a patch." Personally, I will never even remotely consider installing Galaxy for any reason, and if Galaxy is ever required, I will never purchase another game here.

Yes, I finally launched Galaxy (I have it installed but never use it), and I could upgrade the game to 1.02. It seems the 1.01.1 patch was never available offline.

I'm not sure if that patch was ever available offline. I always download the new offline installers every time a game is updated because I archive them and I prefer to keep everything up to date without patching any more than I have to.
