node wants to access key "adobe licensing information" the authenticity of node cannot be verified

last year there was a user that received a similar message while trying to use acrobat:

https://community.adobe.com/t5/Acrobat/Can-anyone-tell-me-why-I-am-getting-this-pop-up-and-if-it-is/td-p/10152752

but i don't know if both of you have been hacked or both of you are seeing a valid adobe triggered message.

i recommend either contacting adobe support or:

1) reset the cc app: To reset the Creative Cloud desktop app, make sure it's in the foreground, then press:

Win: Ctrl + Alt + R
Mac: Cmd + Opt + R

2) if that fails, do a clean cc install:

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
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
