Photoshop is in Creative Cloud versions and it is not available for purchased.
It uses a subscription scheme.
You download the Creative Cloud desktop from Adobe web, when downloading Photoshop or any other app.
This litttle app installs when accepted. And opens and shows a tab with a long list of Adobe applications
There you select Photoshop and click on a button at right that says Install or Try (if you have not subscribed yet).
Thus there are no set up exe files to install.
Are you also sure your hardware matches the requirements?
This looks like a fake/pirate version.
To do it legitimately, you download and install the CC app as described above, and install Photoshop from there.
