I just bought a PSR-800n and already I LOVE it. Gets in signals my Unidens couldn't even touch. I can figure out how to program most things manually on the radio. But it would be easier to do somethings with the EZ Scan software. So I tried to download it to my computer yesterday and I couldn't. Put the CD ROM in my computer (OS Windows 7) and when the screen came up to install the EZ Scan software I just heard a lot of noise on my CD Rom drive then a message came up "Error Code 740 Error Launching E\software\setup.exe". I tried restarting my computer, no go. I put in a music CD to make sure my CD ROM drive works and it does. So what gives??
