Not sure to understand your problem?
Did you succeed to download and install Sweet Home 3D from Microsoft store?
If it's not the case, please click on the link [url=ms-windows-store://pdp/?productid=9NBLGGH2SMTQ]ms-windows-store://pdp/?productid=9NBLGGH2SMTQ[/url] which should open Microsoft Store application and show Sweet Home 3D, sign in with the icon at the top right of that page and it should propose you to install Sweet Home 3D. If clicking on the previous link doesn't work, try to open it in Microsoft Edge or go to Sweet Home 3D page in Microsoft Store application.
