I am having the same problem
. I don't have a screenshot of the error but, I can tell you that I get a small error box in the center of the screen that says "access denied".
I had to take the computer down & move it (wife got "let's move all of the furniture again" disease last night! My kids were thrilled!). I am about to set it up now and run the sp3 update again after I run MBAM, Spybot S&D and SuperAntiSpyware. The system is running AVast Antivirus (free edition) real time and I'm using Comodo's free firewall protection. I turned off all real time anti virus protection in Comodo's free firewall suite to avoid conflicts with AVast. So, the only thing running in that package is the bi-directional firewall.
My system is:
Dell Dimension 2400
Windows XP - Last clean install was within the last three months. Used Windows install discs. I got rid of the Recovery partition and Dell's Utility partition. They're nothing but clutter.
80GB hard drive
I am using Microsoft Update, not Windows Update on my attempts.
PS - If my machine is clean and I still can't install, I'll post the error message here, then follow dfiore's suggestion.
