Can't install the editor in Windows 11 due to Folder Protection issue.
It looks that in Windws 1& with Bitdefender installed there's no way to disable it.

I don't have BitDefender, but I have installed the Editor after updating to Win 11. If it isn't possible to disable BitDefender, maybe you could uninstall it for the time it takes to install the programs you need?
Other things that come to mind: Are you logged on as the computer Admin? Have you tried to right-click on the installation file and choose 'Run as Admin'?

There are option to stop your firewalls. When you go to the settings of Windows defender. You can check privacy and protection option. On that you can untick the real-time protection and try to install your program again.

This may help you,
