Microsoft VBScript runtime error Code 800A0046 line 49 , Char 1 "Permission denied"

[Jeffrey Smith]

I'm using a script to clear Temp files and folders developed by Michael Harris and posted at:

https://groups.google.com/forum/#!topic/microsoft.public.scripting.wsh/j7e2oL0F0pY

It has worked for me since I re-installed Windows 7 a couple of weeks ago but has suddenly started giving me this error:

Microsoft VBScript runtime error Code 800A0046 line 49 , Char 1 "Permission denied"

(Note: I had actually had this happen to me a few years back, so I don't know if this is an intermittent problem or what conditions make it happen)

This is the code (Note, too that I get the same error when I try to open Microsoft Windows Based Script Host, so this was opened with Notepad):

I'd appreciate any insights.
