Hi, I have stumbled upon the same issue with the .msix packages not recognised in my Win10 OS (btw I did comply with the specs).

For some reason, I could not even install App Installer from the Microsoft Store. Eventually this is how I managed to install the Affinity packages:

- open Powershell as Administrator

- type the following: ADD-AppxPackage -Path <filepath>

- substitute <filepath> with the full path to your installation file (e.g. "C:\Username\Downloads\affinity-photo-2.0.0.0.msix")

Voila. Hope it helps!

Cheers.

You have just saved the day for me – thank you for this super simple workaround!

Just two question: Where does this install the files exactly?

You know that is one question, right?

It's a Microsoft OS sandboxed (hidden) folder. To find it Run the application, start task manager, find the application and right click. Choose open application location (or some such, sorry I'm on my phone). That will show the apps location BUT it's a deliberately hidden folder with very special permissions so don't change anything. You should not need to find the application itself, if you want to run it just type this as a command

AffinityDesigner2

AffinityPhoto2

AffinityPublisher2 

And the appropriate application will start (accepting files on the command if you wish)

Hehe, it's a test of whether anyone here reads this conscientiously at all. You passed. 😜

Thanks, I'll take care! It seems that this is not necessary at all. I remember that in previous versions and updates my LUT files and other adjustment settings were unfortunately always forgotten/lost and I had to retrieve and copy them again myself into the new structure. This time it worked with the transfer.

I came across this forum while looking for solutions to a different problem. It is also related to problems opening MSIX files. This is a modern way I put together that is working to get MSIX files working in Windows 10. IT has been tried in 1809 to 22H2.

open PowerShell and run as an administrator. This will make the c:\files directory if it doesn't exist

[System.IO.Directory]::CreateDirectory('c:\files')

Run this command in the PowerShell window to download the MSIX bundle from Githib. It seems to be throttled and takes a while for 250MB file.

Invoke-webrequest https://github.com/microsoft/winget-cli/releases/latest/download/Microsoft.DesktopAppInstaller_8wekyb3d8bbwe.msixbundle -OutFile c:\files\appinstall.msixbundle

Open command prompt as administrator and run the following command:

Dism /online /Add-ProvisionedAppxPackage /packagePath:c:\files\appinstall.msixbundle /SkipLicense

Log out and log back in. Your computer will now be able to understand MSIX file types. If that was the root of your various issues, this should really help.
