[RESOLVED] [2005] changing registry in vista

[.paul.]

i've got a program i wrote in win xp that changes a registry value

Public regShell As RegistryKey
Public regKey As RegistryKey = Registry.LocalMachine
 
 
'' set startup options
If RunToolStripMenuItem.Checked = False Then
   RunToolStripMenuItem.Checked = True
   regShell = regKey.OpenSubKey("Software\Microsoft\Windows\CurrentVersion\Run", True)
   regShell.SetValue("screen capture", Application.ExecutablePath)
Else
   RunToolStripMenuItem.Checked = False
   regShell = regKey.OpenSubKey("Software\Microsoft\Windows\CurrentVersion\Run", True)
   regShell.SetValue("screen capture", "<NonRun>")
End If

this worked well in win xp, but now i've upgraded to vista, it causes an error:

'attempted to perform an unauthorised operation'

how can i rewrite this so it doesn't cause this error?

thanks
