OKAY, I've found the answer:
My actual install IS at 1.6 and 1.5, but I downloaded no cd cracks for both EXEs because I was too lazy to install Daemon tools to mount an image and it's 2019 so I don't want to play with a damn DVD in my drive lol. Turns out these particular no cd cracks were for previous versions. When checking the details of the original EXEs, they ARE the most updated versions. If anyone ever has this problem again, tell them to be sure to get a no cd crack that is the latest version.
