Hello, thank you for reaching out to Microsoft Q&A.
May I please know whether you’re able to download or install other applications from the Microsoft Store?
I recommend temporarily switching your default network from your current Wi‑Fi to a mobile data connection, such as a mobile hotspot, and then trying to download the app from the Microsoft Store again. Check whether the download works when you’re connected to a different network.
If you are still having issues, here's what you can try:
Method 1.
Reset Windows Store cache-
Click Windows + R key, type winver in the run dialog box, and click Enter.
Wait for the Microsoft Store to appear automatically.
Method 2.
Uninstall any other cloud services you have installed, such as Dropbox or Google Drive. If you are already using cloud services on your Windows PC, you may encounter errors when downloading or installing iCloud. You can temporarily uninstall them to see if this resolves the issue.
Method 3.
Re-register Microsoft Store.
Exit the Microsoft Store if opened.
Click Windows + X key, select Terminal (Admin). Run the command below and click enter.
Get-AppxPackage -AllUsers *WindowsStore* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Let me know if you still need more help.
