I thought on CS4 installer had the installation media in it so when the adobe page said to uninstall, I did that and the installer disappeared.
So am I totally out of luck? How did I get here? I updated the OS to El Capitan then had troubles of it shutting down overheating. Took it to an authorized Apple fix it place. They put on a new hard drive and they put my info back on with my Time Machine. Then Adobe products wouldn't work. Go through the steps online on what to do and of course didn't deactivate Adobe serial # because of ignorance when I took it into the shop. I didn't get the steps to work.
Before I uninstalled, I wrote down what was in the preferences/Adobe Systems/Product licenses_120/ B2B43000.dat and 4 other like files that end with .ff1 Is that helpful at all? I can get proof from the Apple fis it place to verify what happened. Will that help?
I don't do web site development any more but still use the products for personal needs so I still want it. I think I just downloaded the CS4 update and didn't I have a hard copy.
Branching to a new discussion.
Tell everyone you know who owns a Mac, including Apple employees... Mac Migration and Time Machine DO NOT WORK properly with Adobe program activations due to hidden registration files that are not included when Migration or Time Machine make their copies
Sometimes helps... Error 150:30 License fix https://helpx.adobe.com/x-productkb/global/error-licensing-stopped-mac-os.html

When you have a non-functioning computer and can't deactivate, use the link below
Serial number and activation support (non-Cloud) https://forums.adobe.com/thread/2041990 to adjust activation count
CS6 and earlier programs have not been tested and will not be updated to run on Mac El Capitan
-which means that you try to use CS6 and earlier at YOUR risk of having problems
-you may get CS6 and earlier programs to install and run, or you may not (some do, some don't)
Install CS5 on Mac 10.11 https://forums.adobe.com/thread/2003455 may help (also for other than CS5)
-also a TEMPORARY security change https://forums.adobe.com/thread/2039319
-and more on gatekeeper https://support.apple.com/en-au/HT202491
You can also download the trial version of the software thru the page linked below and then use your current serial number to activate it.

CS4 and earlier can no longer be activated, so installing is pointless.
--See John Waller reply dated 1-1-22 There's a kink in the space-time continuum with CS4 activation.
Although the CS4 activation servers are officially dead, CS4 can still be activated for use on a fresh install on a computer where CS4 has never previously been installed. I successfully activated CS4 myself a couple of months ago just as a proof of concept
