Can't install Adobe Photoshop! Please Help!

Which version of Photoshop  -- PS Elements 2023 or Photoshop CC 24.2?

On the off chance you're trying to install a legacy Creative Suite product, it won't work on a modern Mac.  CS is too old and not compatible with Catalina, Big Sur, Monterey, or Ventura... 

make sure you meet specs, https://helpx.adobe.com/creative-cloud/system-requirements.html

then, if you do, install the cc desktop app from here https://creativecloud.adobe.com/apps/all/desktop?action=install&source=apps&productId=creative-cloud and use it to install your adobe subscription and trial programs.

if you have trouble downloading the cc desktop app or you see an error message when trying to install, make sure you have a compatible os (https://helpx.adobe.com/creative-cloud/system-requirements.html), and use the alternative download links at page bottom here, https://helpx.adobe.com/in/download-install/kb/creative-cloud-desktop-app-download.html
