Unable to complete re-install of Photoshop CS6 extended on new Win-11 PC

you may need to use compatibility mode to install and/or you may need to repair and/or update your visual c++ versions.

I've seen this reported by other users on Win11.

CS6 was built for use on Win XP & Win7, not Win11 with all the latest security enhancements. There could be a problem with other apps like your antivirus or firewall that are blocking your ability to connect with Adobe's servers.
