32 bit synths don't work with 64 bit Sonar (at least to my understanding and experience). Anyway, I figured out the problem. There's a cute little application called unins000 that has to be in the Dimension folder in the Program Files (x86)/Cakewalk folder for it to work. It was in the regular Program Files/Cakewalk/Dimension folder, just not the (x86) version. Copied and pasted it in, whoopee-whoopee-whoopee. Thanks for all the help.
