Thank you for the quick reply response. Unfortunately, I have tried what you suggested by making a Radar Contact new folder and pointing the unzip process to that folder. I get an error message every time I try it, which has been several, and on three different computers, one Windows 7 and the other two Windows XP. I have also downloaded two different unzip programs and been given error messages by both of them. I have also tried copying and pasting all the files found on the CD to the Radar Contact folder and proceeding to try to unzip from there. Once again, all these methods have been tried on all three computers. I am by no means any sort of computer guru, but I have unzipped hundreds of downloads on various machines and never had a problem such as this before. I do not know if there is a problem with the CD or what, but I do know that I am unable to get the program off the CD with any method I have tried. I am also a previous user of Radar Contact with the version 3 edition which I got from a CD you sent.Please advise as to where to proceed from here. Thanks for your help,BobRogers, Arkansas
