I've had about 15 failures, after trying everything listed on the Microsoft website. No matter what I do I keep getting the "NO_INTERFACE(0x80004002)" error. Service Pack 2 isn't listed as an update in my Windows Updater (and I've checked and made sure I'm not already running it). I've run the System Update Readiness tool as well, with no luck. I was trying this disc because of this response:
"in order to fix this problem ....you have to uninstall antivirus programs......stop all non microsoft services, using msconfig.....insert vista sp1 cd ..that came with the computer.....run setup.exe.....click 'install'....then it asked if you want to install with updates....select not at this time..after you do a clean install, your programs and media should still be intacted. this process takes 2 or 3 hrs. after install.....click start, run , type services.msc ....stop windows update service. now install standalone vista sp2 file ....its about 348 mb....it should work....once everything is installed, restart. and turn windows update back on....thats it! ...i was on the phone with microsoft for hours and we finally got it by following these steps."
Thanks again for all your help~
