I'm hoping you can help...I can download the DMSetup.exe file. When I run it, I am prompted to allow it to continue under the User Account Control, which I do. Then it brings up the McAfee Installer which tries to run, but it keeps telling me my Internet connection is unavailable. I am connected to the Internet, can surf the net, open Web pages, download other files, but this program will not recognize the Internet on this computer. The McAfee security suite downloaded fine on two other computers. I am running Windows Vista Home Premium (the same as the other two computers), the Windows firewall doesn't show anything blocked, any suggestions? Thanks!
