Permission / Advanced Security Settings issue with Program Files

Apologies if this topic has previously been discussed, but my search didn't yield helpful results.

In attempting (unsuccessfully) to install a citrix plugin for remote desktop, I'm discovering that advanced security settings for Program Files are screwed up, but I am unable to adjust them. I am currently logged in as administrator and user account control settings are set to "never notify". Please see the attached screenshot. Thanks in advance.

I'm one step farther in than you. If you choose "change permissions", you'll see the screen that I posted. Problem is (or at least I suspect), "Add" "Remove" and "enable inheritance" are unavailable for me. I have logged in with the "hidden" administrator account, with no success.

If you want to change permissions of a file or directory you may need to take ownership first. So you could try to change the owner to your user profile and apply, You then may have to grant yourself the authority to make your change (so add full control for your profile for example).

Then you can change the permissions to whatever you want.

Once you are done you can remove your profile and then change owner back to "NT SERVICE\TrustedInstaller" or whatever it was to begin with.

Owner of Files and Folders - Change in Windows 10 - Windows 10 Forums

Note that only Program Files directory itself is owned by Trusted Installer. Sub-directories may not be - I have some owned by SYSTEM (for example 7-zip), some by Administrators group (for example MS Office), some by Trusted Installer (for example Windows Defender). You should therefore make a backup and be careful with using inheritance and of replacing owner of child objects so as not to mess everything up

I use Cisco VPN (and Cisco WebEx) and have not had to change any permissions and mine look like yours though so perhaps it is another issue.

Thank you, lx. With different ownership, I was able to change security settings on the folder that was preventing my installation.
