I downloaded the game but can´t play it . I find a lot of files in the !Downloads folder which end in .download , so my guess it the game is downloaded but not installed ? Also i want to install the game on my SSD , but the download files are located on my HDD, I set the install folder to my SSD in GOG galaxy , might that be the problem ? I just don´t know how to install the game, and pls don´t say redownload it because that would take me 3 days :/

Would apreciate any help!

Try downloading patch 1.02 separately, and manually installing it.

Running the patch separately works for some people, however, if the patch says that it couldn't find the directory, then you might have to enter missing registry keys so it can find the game. Galaxy didn't enter TW3 into the registry for a lot of people, myself included.

Here is a thread with information about the registry entries, if it turns out you are missing them:

I´ll try , thanks for the help !

So i read everything and tryed to download the patch but it didn´t work, i think the problem is that the game didn´t even install, any idea what i can do ?

my files look like this

Do you have (setup) file?
Patch file needs to be in same folder.

Those look like localization files, where did you install the game? Make a screenshot of that folder?
