Hi All,
Hope someone can advise where I have gone wrong , downloaded version 022 and get error message

I was using 018 without any problems.

Someone a few months ago was having similar trouble when their anti-virus software was running:

Hi,
Thanks for the response, the problem is I have the arduino loaded onto my laptop with Win 7 also with
the same anti virus program and it runs just fine.
I cant understand why it wont run on the desktop with XP ???
