what do you mean with install? The game is inside a standard zip data. You open it with WinRar or whatever archiver you are using, unzip it, and double click on "game.exe"
I mean that when I am taken to the download page. I click to download the game. And it only allows me to download the walkthrough. Not the game. Returning to the download page while walkthrough is installed, to download the game, results in me unable to select anything.
After some tweaking around, and installing a 40 trial of winrar, I have managed to launch the game. Will update if anything goes wrong, thank you for the aid.
