Hi jk8028,
Thanks for your post. Please contact Sky Go support at first to see if there is any requirements or compatibility issue with Windows.

Also, based on my research, please verify the previous application has been uninstalled successfully.
Uninstall the Sky Go app and then go to 'C:\Users[your user name]\AppData\Roaming (ensure hidden files/folders are visible) and delete the following folders: Sky Sky Go And if it is present the Cisco and/or Synamedia folder in App\Data\LocalLow. Empty your recycle bin.
Reboot your PC and then download and install the Sky Go app again.
Best Regards,
Ian Xue
