I am working on a Protek P4 computer with 128 mb purchased earlier this year through Popular Club.  The computer case has the official Microsoft Windows XP Home Edition Lan Plus STICKER with the 25 digit serial number.  When I attempt to install XP Service Pack 2 from the official Windows XP Service Pack 2 CD, I get the following errors: Setup Error  The system cannot find the file specified.  I click OK and get a 2nd Setup Error  installation did not complete.  I click OK and the setup routine stops.  I also attempted to install SP2 from an ADMINISTRATIVE download, with the same result.  This computer has no internet access.  Does anyone know why this is happening, and how can I resolve this problem.Well, first off, you really SHOULD have 256 MB of RAM to be running Windows XP on ANY computer... For the download problem, do you have a firewall running? If so, try temporarily DISABLING it.

[glb]Flame[/glb]if you have any anti-virus programs disable them......now load the cd......If you can get to the internet check out this site http://www.michna.com/kb/WxSP2.htm

I know what you are TALKING about, some of my Dells at work was having the same issue.  Hope this helps.If run a spyware/adware SCAN before you install sp2, you should have no problems.  It worked for me.
