Hi

Try to do this:
  • Set IE as predefinite by using the Control Panel -> Default Programs -> Set Default Programs
  • Run OblyTile as Administrator
  • Click the Rebuild Cache button
  • Create a tile
  • (Optional) Check if the tile has been created
  • Set your favorite web browser as predefinite by using the Control Panel -> Default Programs -> Set Default Programs
  • Run OblyTile as Administrator
  • Click the Rebuild Cache button
  • Create a tile

Hope this helps

Argony.
