I have run SFC /SCANNOW all protected windows files are intact and in their original versions - at least I think so. I only have a Windows XP Home Edition Service Pack 1 Recovery CD from MESH Computers. Is this OK?
Restarted computer - tried to download and install both security updates with NIS disabled but still have the same problem.
Followed your instructions and got to the "Blue box" When double clicking on either file title Q329170_WXP_SP2_X86_ENU or Q810833 etc, the Windows XP Setup Wizard flashes on/off. I then receive the following error message:
Title: Q3291709 or Q810833 Setup Error
Text: Setup could not verify the integrity of the file Update.Inf. Make sure the crytographic service is running on this computer.
Tried to search "Help" using the word "Crytographic" which returned no results.
Stuck once again - thinking of throwing this computer out of the window!!!!!!!
Hope you can tear yourself away from the telly to help me again.
