Awesome! The 1.2 patch installs automatically.

Speaking of patches, I just had a great idea that would make patching easier, play nicer with mods, and allow easy rollbacks, even partial ones:

Use a real version control system, like git. Install it with the game, and give the user a nice tool that allows him to pull in patches, rollback individual features of patches that he doesn't agree with, stash or rollback mods in order to avoid conflicts with a new patch, etc.

In retrospect, it's so obvious that it wouldn't surprise me if some game developers didn't already do this.

IIRC, the last system I remember that does what you allude to is WC3. It was un-official but someone made an app that allows us to update, rollback, stash and basically what you just mentioned. I agree that it would be very useful to more advanced users but most people wouldn't care for this unless some mod kits are distributed like the Adventure Editor from TW1.

It was telling me "Patcher 1.2 is ready to install" and doing nothing.
I had to run TW2 in Admin Mode to get the automatic patch 1.2 to install itself.

Wouldn't it be enough just to create an installer which would backup changed files and when uninstalled revoke changes?
Use InnoSetup. I'm sure it has all needed functions.

Downloaded quickly and installed without issue, something finally worked, I need a lay down to get over the shock.

That's basically what a good version control system does. Although git stores only the actual changes, which could be a lot smaller than the complete files. My point is that game developers don't need to invent their own system to distribute and install patches; they could just use an existing system: have their launcher call git to install patches automatically, and as a bonus, advanced users get a lot of extra functionality for free.

Yeah same thing happened to me, I went to the Witcher 2 site and manually installed it. It's all good just an extra step though.

Mine wouldn't autoinstall so I just went to the Documents\Witcher 2\Downloads folder and ran the Patcher_1.2.exe file manually. Worked fine.

have you tried closeing it then opening again
