Is it possible to put photoshop or any adobe software on a flash drive and run it with the ability to save files? and if it is, would it be againist Adobe's terms of service and would my plan be violated? I'm mainly talking about if I want to get some work done and my primary setup is a desk top which isn't portable. Could I run the software on a library computer or friends laptop?
For those in the future that find this thread, this is wrong. You can run Adobe apps off a bootable USB drive. I run Catalina as my main OS, but have a bootable drive running High Sierra to use my CS6 Suite. Except for the slower initial OS boot speeds, the apps run just fine. As an occasional user, I have no need or desire to upgrade to CC and the monthly subscription costs.
Install it(portable) in a bootable usb, its works fine with windows also. you no need any user account in your friends computer. It will bott from your USB and it will be working with admin rights. Means you can use the computer but not his drive(HDD/SSD).
