I tried different routes to get to the install page and say its unavailable right now. I've even tried in a different browser .
Which Adobe product are you trying to install?
photoshop and illustrator
follow the directions given previously.
if you're trying to install any subscription app, install the cc desktop app, https://creativecloud.adobe.com/apps/all/desktop?action=install&source=apps&productId=creative-cloud
if you're unable to download the cc desktop app at this stage, use the "alternative download links" at the bottom of the page at https://helpx.adobe.com/download-install/kb/creative-cloud-desktop-app-download.html
use the desktop app to install your cc programs/trials
if you're trying to install a non-subscription app, answer @John Waller
