I have never installed the 32bit version of Photoshop CC 2018 and I have been using Wibdow 10 for years so I can not address Windows 7. There is a Windows 32Bit Photoshop CC 2018 the direct installer may still be downloadable Adobe cc 2018 direct download links
So If you have Photoshop CC 2018 installed and activated it will run. However, Adobe does NOT stop older version from running. That would be Photoshop CC 2019 and Photoshop 2020. And these days Adobe only has the latest two version of Photshop available for installation via the creative cloud desktop.
