[2005] Append exe onto exe?

[knxrb]

How would I get it to delete the file after it has finished running?
I tried adding this code after the 'Me.gameloaded = Process.Start(file)'

                Me.gameloaded.WaitForExit()
                If My.Computer.FileSystem.FileExists(file) Then
                    My.Computer.FileSystem.DeleteFile(file)
                End If

...but it didn't delete it!
