"I Cleaned all the malware and trojans off the machine and the Service Pack installed."
Another person had to uninstall all antivirus and such protections.
I have three XP computers (described in my profile). On one SP3 installed fine right away. On the newest one, after much trouble and with the help of others, I got everything to update and download:
On my system with XP Home, I get the following error message when I go to the update site and SP downloads fine but fails to install and gives the same error message as follows:
"The file c:\windows\system32\smss.exe is open or in use by another application. Close all other applications and then click retry."
No other applications are ever running when this occurs and I am baffled by it. Anyone got any ideas how to fix this? Thanks.
