I cancelled my adobe acrobat dc because even with customer help it would not download and run. A waste of money.
the computer tells me it has 5.87GB of usable RAM out of 6.00; and 589 GB of disk space; 3.30GHZ processor; 64 bit Windows 10; Chrome; 1920x1080 screen resolution. This appears to meet adobe system requirements according to the link you sent. Other ideas?
it's hard to give more than generalites without more info from you. eg, you say you could not download and run.
if you couldn't download the installation program, then you couldn't install it and therefore you couldn't run it. if that's what happened to you, did you install the cc desktop app from here https://creativecloud.adobe.com/apps/all/desktop?action=install&source=apps&productId=creative-cloud and use it (try) to install acrobat?
if no, what did you do?
if yes, what exactly did you see when you tried to install acrobat using the cc desktop app.
The download has been stuck at 84% for 55 minutes
perform all applicable steps:
uninstall every cc app including preferences, https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html
then uninstall the cc desktop app, https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html
clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html
check for, and if available, update your os
restart your computer (don't skip this)
reinstall the cc desktop app, https://creative.adobe.com/products/creative-cloud.
if you're unable to install the cc desktop app at this stage, use an administrator account (solution 4 here, https://helpx.adobe.com/creative-cloud/kb/creative-cloud-missing-damaged.html)
use the desktop app to install your cc programs/trials
