Hello Ron and Rosemary, A belated thank you. At last, today, I have fixed the above error & am now able to download & install Windows Vista updates. I achieved it with the help of your email dated August 18, plus a variation on instructions accessed on http:// www.ehow.com/how_8680831_rid-catroot2.html It is great to be able to install the updates, as I had been unable to do so for two months.

Whether you act upon these suggestions is a matter of what level of risk you are prepared to take as you are meddling with the system files which can be a very risky procedure. If you do decide to take this root make sure that you have fully backed up your PC before you do anything and be prepared to re-name the files back again if it doesn't work. I have once done a similar thing in Vista when the file holding my password became corrupted and it was a bit of a last ditch effort to regain control of my laptop! But I would certainly not do it if I had another choice. Bye Ron M :-) No virus found in this message.
