that's a window's error. you could google the various solutions including repairing/updating your .net framework.
or you could try:
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 using admin account*
use the desktop app to install your cc programs/trials
*for info on how to use admin account, see solution 3 here, https://helpx.adobe.com/creative-cloud/kb/creative-cloud-missing-damaged.html
thanks for your answer.
I did both of your solutions. both doesn't work
Are there any other ideas?
