Mario Kart Wii not being "read"

[Jack]

• Where is Dolphin located? If it is placed in Program Files, that may be why this is appearing.
• Make sure you have the permissions in Windows to read/write to the Dolphin Folder located in My Documents.
• Try running Dolphin as admin.
• Also make sure that your Anti-Virus is not blocking Dolphin.
  

If all this doesn’t help, then open Dolphin > Right click on the icon of Mario Kart Wii in games list > Properties > Verify > Verify Integrity
And then post the screenshot of the result here.
