Answer 1

You are trying to delete a file that does not exist!

Clearing Prefetch files could be done in VB.NET like this: *Imports System.IO

Dim file As String
For Each file In System.IO.Directory.GetFiles("%systemroot%\prefetch")
System.IO.File.Delete(file)
Next file 

To avoid geting any error:

Try
 Dim file As String
    For Each file In System.IO.Directory.GetFiles("%systemroot%\prefetch")
    System.IO.File.Delete(file)
    Next file 
Catch ex As Exception
    msgbox("Can not delete Prefetch right now!")
End Try

Well please run your app in Admin Mode (in win7 and 8)
