Before discussing the download process, let’s understand the demand. Why would anyone use a 20+ year old image editor?
Instead, try (for immediate browser-based editing) or GIMP (for a desktop experience). If you absolutely need the classic Photoshop 7.0 feel, find your old CD or use a licensed copy on an offline, air-gapped machine.
The primary issue with searching for this software today is the source. Because Adobe no longer supports or sells Photoshop 7.0, it is not available on the official Adobe website. This forces users to turn to third-party software archives like Softonic.
For most educational or production needs, choose a supported modern editor (Adobe subscription or robust alternatives like GIMP/Affinity) rather than attempting to download an old Photoshop 7.0 installer from Softonic or similar sites. If you legitimately possess the old installer and license, run it only in an isolated VM and scan thoroughly.
