I installed the software on 5 PCs. Three of them went without a hitch. I have two left and cannot get them to load properly. The install semms to go fine, but after I reboot and try to open the program it closes down on me. One of the systems is running Windows XP media center 2002 and the other is running Windows XP Home Edition SP 2. I have gone through every troubleshooting procedure I could find and have had no success. The Boot and Malware cleaner also fail and close down on the WMC. The WXP will not allow me to stop the service. Can someone please help?
