Sorry to hear about the trouble. This error generally occurs when the system failed to lower privileges. Please try the steps shared on this help article: https://helpx.adobe.com/in/creative-cloud/kb/troubleshoot-download-install-logs.html
Let us know if this helps or if you need any further assistance.
What privileges are not being lowered? I am the administrator of my computer and work for IT with the Department of Veterans Affairs. I know there is a whole group of Medical Media departments through out the VA with Windows 10 PCs having the issue and migrating over to an Mac is not an option.
We're so sorry to hear about the trouble. Could you please confirm if you have an enterprise account? If yes, I'd request you to log a support ticket with them.
