I used the restore discs to restore an old Compaq laptop running XP. Everything installed like it should. However after I downloaded Avast Anti Virus I get a message that says "This application has failed to start because the WINHTTP.dll was not found. Re-installing the application may fix this problem" I reinstalled the restore discs again and I got the same error message. I cannot do any Windows updates either. It says I am unable to access the Windows Update website from Windows XP, Windows 2000, or Windows Server 2003. I tried to dl and install the XP Service pack 3 but it says the Service pack I have installed (which I do not have any SP installed) is lower than what is necessary. At minimum I need Service Pack 1 installed. Does anyone have any ideas how I can get this machine back running? Where can I get a copy of Service pack 1 for XP? Or is this Microsofts way of saying it is an old machine the they dont care anymore. Thanks for any and all help.
