Sorry the apps don’t support Windows 8.1. You need Windows 10 May 2020 (build 19041) or later. 

OK, thanks for that Mark.

Great news about the MSI installer!

Will this will mean that it can be installed on Windows 8.1, or is there some other reason that would prevent this?

The installer isn’t the problem here - unfortunately we don’t support Windows 8.1 (the minimum we support is Windows 10 May 2020 update). If you can’t update your OS I suggest you seek a refund. Sorry. 

That's a great shame. I guess I'll just stick with v1. Have sent an email for a refund.

Another vote for a standard installer. I can't install .msix on Windows 8.1 (yes, I know ...).

Hoping this will be sorted soon, otherwise I'll have to ask for a refund before the 14 days is up.
