Hi, i bought a original CD with Adobe Photoshop CS2 in 2007. I just installed it,
but i can not activate it. Is this version too much old for activation in 2017? Thank you.
Note also that you must use the key given on the download page listed above, not your old key - it will not work.
... And that is assuming it will run at all under your new OS.
As the other guys have said, download the version that has had activation removed, use the 'new' generic product key. You should have no problem with Windows but it will not run on a Mac with an Intel processor.
