Switch: If there is no 64-bit version available, or there is one but it's not compatible with Catalina, is there some other, similar program that you could switch to?.

Your goal is to answer the following questions: If the current version of the program is 32-bit, is there a newer 64-bit version? If so, is it compatible with Catalina, and is it free or does it cost something?
