plug-ins

I am trying to instal a plug-in auto-tune. I have tried gsnap and Graillon 2. Every time I cannot proceed because it gives me a message “You’ll need to provide administrator permission to copy to this folder” (the plug-in folder). I have followed the instructions as per a tutorial to the letter but withouy success. Please help or give permission.

[u]The Antares website[/u] says AutoTune does NOT support Audacity.
