Windows 10: How to install Windows 11 on an iMac without Bootcamp?

So, I really want to install Windows 11 on an iMac without Bootcamp. I downloaded the application "Windows11InstallationAssistant.exe" from the website: https://www.microsoft.com/en-ca/software-download/windows11 . When I try to open this application, I get the message "You can’t open the application “Windows11InstallationAssistant.exe” because Microsoft Windows applications are not supported on macOS."How do I install and run Windows 11 on an iMac without Bootcamp?

iMac Bootcamp Product Key Problem

So I had an iMac that had Windows 10 downloaded via Bootcamp. I no longer use that iMac and instead, use a computer with inactivated Windows. The iMac Bootcamp had a product key I bought from a store and I want to remove it, but I lost the boot drive to
get into Windows on the iMac. Could I just delete the Windows Bootcamp partition on the hard drive to remove the existing device that uses the product key?

Windows Install on iMac

Greetings;

I have a iMac Mid 2011 Intel Core i7. Running OSX 10.10.5 Yosemite with 16GB Ram & 748GB free space. I would like to install Windows 10 and then install Office Professional 2016. It appears I would not be able to install Windows via Bootcamp, as my machine
is not listed as being supported. However, my iMac does meet the requirements to install Parallels Desktop 12. Would I be correct in assuming that after purchasing PD12, I could install & run Windows 10 that way?
