If you're interested in trying out Adobe Premiere Pro CS4 Portable, you can download it from various online sources. However, be sure to only download from reputable websites to avoid any potential malware or viruses. Once you've downloaded the software, simply extract it to your portable storage device and run the executable file to launch the program.
The risks of malware, legal consequences, data loss, and sheer technical frustration far outweigh any convenience of portability. If you need a portable video editor, use modern, legal, open-source alternatives like Shotcut. If you specifically need Adobe Premiere, subscribe to the current Creative Cloud version (or buy a legitimate old license if you must run CS4 on an older machine), but recognize that CS4 is a dead product unfit for today’s workflows.
