I bought the game off of Amazon, and got a download link for rct2. After trying to install OpenRCT2 for about 20 minutes, I started watching tutorials on Youtube, which didn't help, as the program would not be able to detect it, even after reading the 'README.txt' and naming files different things as a way to trick the program into thinking I bought it off of steam didn't work, is there any way to Install with the Amazon download link? Thanks in advanced!
