Nope. Toss your installation disks in the recycle bin and move on. CS4 is officially dead.
The activation servers are gone. Even if you manage to get the 15 year old installers to work on Windows 11, you can't activate the software beyond its 30 day trial. When the trial ends, so does your access to CS4. Sorry.
