Ok - well I had a go of doing this myself. I didn't use the exact process as the video in the original post to do it, though, as the process has slightly changed now.
Note: if you have already followed the steps in the video you may not need repeat any of the steps - however sometimes completely uninstalling and removing everything and starting from scratch can help resolve issues.
The first step - as shown in the video - is to enable virtualization in your BIOS/UEFI settings for your computer. This is specific to your computer hardware so you'll need to look up how to do this for your hardware. It's not difficult to do - but it is important to get it right and do this step first.
The second step is to enable virtualization in Windows 11 itself. To do this, tap on the "Windows" key on your keyboard, start typing Turn Windows Features on or off, open the program with that name, then scroll through the list and enable Hyper V, Virtual Machine Platform, Windows Hypervisor Platform, and Windows Subsystem for Linux (or whichever ones are available for you). Restart your computer.
I then went to this website - https://www.androidauthority.com/how-to-run-android-apps-on-windows-11-3048569/ - and followed the steps under "How to run Android apps on Windows 11 unofficially" in order to install Windows Subsystem for Android via Powershell (rather than via the Store App - my choice but you could do either way).
I then went to this website - https://www.androidauthority.com/how-to-use-adb-android-3260397/ - and followed the steps under "How to set up ADB on a computer: Windows, macOS, and Linux". Just that section. I recommend putting the "platform-tools" folder under C:\Temp in your computer (so it would be C:\Temp\platform-tools).
Now you want to start up Windows Subsystem for Android app in Windows 11, go to Advanced Settings, then enable Developer Mode. Then go to the System menu and click on the Files shortcut icon on the right to get the subsystem running. Now go back to Advanced Settings and under the heading Developer Mode double check the IP address has been set to 127.0.0.1:58526. If it is different - that's fine - just make a note of what it is.
Now download and place the ASIAIR APK file into the C:\Temp\platform-tools folder. Then right click a blank space in that folder and select "Open in Terminal".
Here's where you will now use ADB to install the ASIAIR APK file in order to run the ASIAIR App natively on your Windows 11 machine. Refer to the attached image to see what I had to do. You can see that, for me, I needed to type things in a particular way.
Also note - while it may seem like it isn't doing anything - you'll need to wait a few minutes while does the "Performing Streamed Install" before it says "Success". You can then exit/close the Powershell window.
The ASIAIR App should now be ready to run.
