Why would you want too. You can not Licence CS4 or CS5. Adobe Photoshop trial period has also been changed from 30 Days to 7 Days. To gain skills download a free image Editor like GIMP and learn how to do image editing.
Yes old versions will install as 30 Trials if you not have a license and if you do not have a license you can not get one for adobe does not market perpetual Photoshop anymore. What good is learning to use a little of something you will not be able to use after 30 days. No one is going to learn Photoshop in 30 Days. It take a long time to learn to use Photoshop well.
Old version also have no support but that not a big deal.

...Because those versions can be easily cracked? I see young people (kids) download very old versions of Adobe software simply because of this.
So your a thief where can Adobe find you... They do not want you to teach kids your ways. Thief's have no problem downloading cracked version of Photoshop Why would they want to download a version that is not cracked. I do not think the OP is a thief...
Wow, wait - are you aiming that comment at me? I am merely pointing out the reason why these requests for older versions of Adobe software pop up on a regular basis on various forums. Whenever I encounter these, I always direct them to free alternatives such as Gimp and Krita myself.
Please don't confuse my answer to your question with condoning that type of behaviour - I certainly do not.
What?! I was simply answering your question why someone would ever want to download such an old version (aside from doing research on older versions of Photoshop - which I can't see the OP here wanting to do), and I am not condoning that behaviour at all. As a matter of fact, the "tools" to crack older trials are riddled with malware and viruses.
The only reason I became aware of these practices years ago is because a small number of students of mine resort to this path, with the end result almost always ending in their laptops becoming bricked/impossibly slow to work with due to the malware, and that affects their work in class, obviously.
And seeing the wording of the OP's message sets off alarm bells, in my opinion.
And now you telling the potential thief's that they would be better off cracking a Photoshop trial version of Photoshop for it come from a reliable source Adobe. That download a cracked version may may be risky. They thank you for the information
I hope what happened to your student tough them more then they should have cracked Photoshop themselves.
Are you actually comprehending what I wrote? I am telling people here the EXACT OPPOSITE: it is just as risky!
Should we not be acknowledging these risks, feign ignorance, and fail to warn (naive) users?
