I had to reinstall XP on my old Tecra 780 using the original disc. I need to run utility software that only works on XP, so I'm stuck with it. But I can't register online, orbit Windows update to run, or download the SP3 update manually. I tried installing Firefox, but it won't install on XP1. The Microsoft download page loads with errors and then becomes unresponsive to. I ran easyfix twice. Any advice? Is there a browser that will install and allow me to use the MS download page, or any place to download the service packs?
