First of all I did the search for my problem but everything about it is old and I never actually saw a fix. My problem is this, I go to the download page for LimeWirePro that I purchased. I go to download it and it does, when the install wizard comes up I get this error message

ERROR OPENING FILE FOR WRITING:

C:\PROGRAM FILES\LIMEWIRE\COPYING

CLICK ABORT TO STOP THE INSTALLATION,
RETRY TO TRY AGAIN,
IGNORE TO SKIP THIS FILE

I have been trying to download this thing for a month and its the same old stuff. What do I need to do to get it installed.
