The most likely cause is that the Spell It app is no longer available or no longer compatible with the new PC, which is why the Get button is grayed out. When an app is removed from Microsoft Store or is incompatible with a device, the Store will hide or disable the purchase/install button, even if it still appears in the library or on another device.
From the documented behavior of Microsoft Store:
- Apps that are no longer available can still appear for a while, but cannot be newly installed.
- Apps that are not compatible with the device will have the purchase/install button hidden or blocked.
Because of this, installing directly from Store on the new PC is not possible when the Get button is disabled.
Regarding migration from the old PC:
- Microsoft Store apps are not supported for manual migration by copying folders from one PC to another. They must be installed and licensed through Microsoft Store on each device.
- If the Store will not allow installation on the new PC, there is no supported way to move the app from the old PC.
To double‑check the general causes on the new PC:
- Confirm the same Microsoft account is used on both PCs and that the new PC is added as a device: see Manage devices used with your Microsoft account and Manage your devices for Microsoft Store.
- Verify the PC is authorized and restarted after any recent Windows updates.
- Check if Microsoft family settings or region restrictions could be hiding or blocking the app.
If the app is still not installable after those checks, it is effectively unavailable for that device and there is no supported migration path.
