trying to download and install photoshop but it just says WAITING...??

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 desktop app, use the alternative download site at page bottom here, https://helpx.adobe.com/in/download-install/kb/creative-cloud-desktop-app-download.html
