This is the message I get when I try to update my Adobe Air.
PLEASE NOTE: I AM THE ADMINISTRATOR AND OWNER OF THIS COMPUTER. AS PER THE PICTURE ABOVE.
What OS are you using currently? If you are using any Windows other than Win 10 please use https://support.microsoft.com/en-us/help/2970908/how-to-use-microsoft-easy-fix-solutions tool and see if it resolves your issues. If you are on Windows 10 go to "Control Panel\All Control Panel Items\Troubleshooting\All Categories" and run the Program Compatibility troubleshooter and select Adobe AIR there.
Let us know if you still see some issue.
I'm getting this same error on a mac. I am the administrator of the computer, so I do not understand the error or how to get around it.
