do i need BOTH Apple Application Supports (32-bit AND 64-bit) on my windows 10 64-bit pc? i saw ONE answer to someones same question but it seemed to be a "guess answer" only... id like a definitive answer please... when upgrading my itunes, etc, does it know what software to also update, and does it mean that my Apple Programs may be BOTH 32-bit and 64-bit and i need to leave both of these on my system?....fyi, they were both installed on 05/17/17 and are both versions 5.5 ... and are 163 and 182 mbs respectively... thank you... too much OCD for keeping my computer clean? lol lol
