I try to install XP Home as an upgrade to 98SE, but it doesn't work. My system passes all requirements - it has 500MhZ PIII, 327MB RAM, 64MB Video RAM, Runs at 1280x960 resolution, has 30GB Free, CD-ROM (obviously), and meets any other requirements. When I install, the thing installs, then reboots. After the reboot, it goes to the XP boot screen, it says "Please wait..." I left it for 3 hours, it wasn't making any noise, except for the cpu fans, and it did nothing. No HD activity, nothing. I reset it, and when I boot XP normally, It gets to welcome screen. I click a user (any one of them) and gives a message box saying that XP is unable to validate the license or something. It has error code 0x80004005, and that is commonly casued by attempted pirating. I can boot in safe mode, but that's it. Cannot activate in safemode. I uninstall, try again. Same. I uninstall, and am using 98SE right now. Help!!!
