As to whether you can install over what you've got (or not got), I'm not sure. You could use/install Windows Installer Cleanup Utility and see if it lists anything for SP3 and uninstall any tidbits with that. I'll bet nothing SP3 appears on the list, though, since your Add/Remove shows 0 bytes. You can grab WinInstallerCleanupUtility here:http://support.microsoft.com/kb/290301
But I can tell you I downloaded the full copy of SP3 and installed it just fine, and I've NEVER installed an SP before! I'm no IT tech and am running one pc at home, not a network of thousands. I did this following Bill Castner's (MS MVP) recommendation on Broadband Reports DSL forums. I got my SP3 at the MS site: http://www.microsoft.com/downloads/details...;displaylang=en
I installed in Safe Mode at his suggestion, so that nothing, especially security apps, would impede a clean install. For the record, I made a CD copy of the full SP3 also and recently had to do it all over again following a reformat/reinstall of OS, like yourself, and the SP3 installed nicely the second time in Safe mode as well. Seems like the process took about 30-40 minutes total, but can't remember for sure.
Hope this helps you. Another more expert than myself may offer other suggestions. Good luck!
