However Photoshop did work yesterday and when I now try to download it I get a message saying that an earlier version will be installed |
You must have been running Photoshop CC 2018 (aka version 19) or earlier, which supported Windows 8.1.
Be aware that support for Windows 8.1 has been dropped in the latest version CC 2019 (aka version 20) released in Oct 2018. That's why the installer is telling you that an earlier version will be installed.
Photoshop system requirements
To install the latest version CC 2019, you now need Windows 7 SP1 or Windows 10 (even some builds of Windows 10 are not supported).
Thanks for response John. However I've now fixed the problem by following a method shown on You Tube and Photoshop is now working ok.
