The link is just the instructions on how to use the Advanced option. On my creative cloud the Advanced Option is never offered.
For example, if I hit Update the update begins and the old version is automatically removed, I never get the option of choosing Advanced Options.
Also no option to reinstall old versions.
I have an active version. And for my second installation on my laptop everything works fine. Both are Windows 10.
uninstall everything cc 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
restart your computer (don't skip this)
reinstall the cc desktop app, https://creative.adobe.com/products/creative-cloud.
use the desktop app to install your cc programs/trials
Thanks. I will update if there is any problem once I do this.
