i installed the game now about more than 10 times and it fails. I did it step by step through different guides, including this one here. It works until RS 2.5, but when i copy paste the RS 2.6 patch i get appcrash to desktop. There are only two differences i noticed so far. I don't have 28 folders to merge, but 21 is shown. And i don't have about 1400 files to merge, but around 800. And then i don't have in my vanilla the folder custom, but that doesn't matter because RS 2.5 works.
