Since the Windows Store app is not on Windows 10 LTSB by default (thankfully), it's not possible to install. To overcome this:
Enable developer mode in Windows 10 Settings app.
Restart computer.
Paste the URL from the Tablet Pro store app into Adguard (
https://store.rg-adguard.net/) & download generated links.
Install the AppxBundle using Windows Powershell.
Done.
