Photoshop/Adobe Suite Won't Install on New MPB

[Gmas]

So I bought a new Macbook Pro, but still have my old mid-2009 MBP which has the full Adobe Creative Suite 4 (including Photoshop) installed on it. I finally located my 24 digit serial number from the old machine, downloaded CS4 again on the new MBP, but when I go to install it, it says that serial isn't valid. The software is legit and still works fine on my old MBP.

Am I missing something as to why this won't install on my new machine? Is there something else I have to do? is there anything I can do to get it working??

You can try to extract the relevant software parts from the installer, but the installer itself is not going to run. And even if it did run, the locations that the installer would try to install files into probably have changed drastically since CS4 was released. And even if you could extract the pieces necessary, it's not likely that any of that software would run on any modern OS.

To be direct: Adobe Creative Suite was released in 2008... it's time to pay for an upgrade.

You already downloaded CS4 from https://helpx.adobe.com/creative-suite/kb/cs4-product-downloads.html ?

You install on Sierra or High Sierra? Don't give up...

As far as I read here on MR, there are even problems with latest Adobe CC versions on macOS High Sierra.
Maybe the OP tries to install Adobe CS4 on Sierra, he doesn't mention to be on macOS High Sierra.
If macOS High Sierra is the problem, I recommend creating an extra macOS Sierra partition to run CS4.

Some times ago I had similar problems to install Adobe CS6, because of Adobe's registration servers that were permanently down. However, Adobe provided on their website an installer including a generic working serial number that didn't need the registration server and one could use instead of an own valid SN. I think that meanwhile the generic installer has been removed by Adobe. If one would call Adobe, I bet they'd state that CS4 is not compatible to whatever recent version of macOS or that they just support it anymore.
One would only find out, if the registration servers are the only real problem when trying to install on some former officially supported OS like Mac OS X Tiger, Leopard, Snow Leopard... If I were @Gmas, I'd keep on trying to find a solution for the source of the problem and not moving directly to the subscription based Adobe Creative Cloud.
