I have been trying to install windows defender. I can download the programme no problem I save it onto my desk top Then when I click on it I get a message saying that access is denied. I have tried downloading with Firefox and as the program I was down loading was from Microsoft I tried with IE7. I have tried saving to my desktop and to a flash drive What ever I do I get the same responce "access is denied" I seem to remember I had the same problem with Another programme that used Windows instaler package. I also cant not install windows critical updates They download but will not install I have run all my security software and done an on line scan, nothing found I have even tried running the programme from source instead of saveing it
To install updates, do this: click start - run - cmd - ok write these commands and click enter after each one (you must get a success message for each one): regsvr32 wuweb.dll regsvr32 wups2.dll regsvr32 wups.dll regsvr32 wucltui.dll regsvr32 wuaueng1.dll regsvr32 wuaueng.dll regsvr32 wuapi.dll I have Windows XP Pro SP2, and had the same problem installing updates. I did this and all went right! Good luck!
