i think the reason why i needed a seperate keygen.exe was because i only had flash pro and xf-mccs6.exe was for the whole suite
looks like you used to be able to download CS6, since https://helpx.adobe.com/creative-suite.html
now reads:>We no longer provide installers for Creative Suite apps. To get the latest versions of your familiar apps that have been tested in current operating systems, upgrade to Creative Cloud.
i checked that url on web.archive.org
and it just linked to either tutorials or help topics. if they had official downloads for CS6 it's buried somewhere.
did find this beast of a PDF with 913 pages of CS6 "help and tutorials": https://help.adobe.com/archive/en/flash/cs6/flash_reference.pdf
hard to believe adobe just threw flash away. was on almost every computer in the world, even came pre-installed with windows. couldn't they have released free tools for making swf files, getting goodwill and funneling people to their other services? a 'lite' version of CS6/Animate perhaps? get people hooked while they were young and as adults they upgrade to the paid version.
