Hello again,
Thanks for the suggestions. I deinstalled both McAfee and Norton, but the first Windows update patch I require (kb3185911) still failed to load, and returned the same error ('the update does not apply to your system').
Unfortunately, I can't find a Windows update troubleshooter for Vista. All I can find are versions for Windows 7 and above. Do you have a link for a Vista version?
IE:
Prior to the general Vista update problem that all Vista users seems to be experiencing, I installed Windows updates regularly, including IE updates, and, as a result, have IE 9 installed, although I've never used it.
Time for a new computer?
Yes. Undoubtedly. However, I'd like to keep this one running a little longer, and want to patch it up as much as possible before the extended support ends.
Do you have any other suggestions?
Thanks
