How to transfer photoshop to another PC?

Question

Windows

I bought a new computer, I want to move Photoshop there, what folders do I need to copy for this?
Or how to download the update to 2015.5. I don't like the 2017 version. Creative storage only offers to download the 2017 version, but no longer allows you to upgrade to 2015.5.
There is a key and an installation file PS 2015.0
If I copy the folder from:
C:\Program Files\Adobe\
C:\ProgramData\Adobe\
do not need anything else? or you have to copy files from:
C:\Users\1\AppData\Local\Adobe
C:\Users\1\AppData\LocalLow\Adobe
C:\Users\1\AppData\Roaming\Adobe

it seems like they are automatically created, which Something like a cache and settings?
I really need it, I don’t want to buy Photoshop again, and it’s torture to work on an old computer.
The support said that I would install my 2015 key and update to the 2017 version .. But I don’t want to. I wrote to them. They are silent for now =(
Maybe you can save me.
Thank you for any help already.
It seems to work, but when I first copied just a folder from \Program Files
Not all modules worked, I didn’t notice right away .. I had to copy \ProgramData
then the camera is equal
, so I asked a similar question .. suddenly I forgot something else and I will get an unexpected surprise.

Answer 1

Enough of what I did and everything works.
You can just copy the adobe folder.
What will not work so download. Problems arise only with the camera equal.

Answer 2

Download installer 2015.5 from rutracker and enter your key tried?
