Since the release of this 'important' Vista patch (KB948109) 2 days ago,
I've made several unsuccessful install attempts. All failed. I still
keep being offered it though.

The patch has to do with SP1 update to the SQL server 2005

(I had no problems installing the other 8 (6 Windows + 2 MS Office) patches.

(I never use this (SQL server 2005), it came pre-installed on Vista
Business. Does another part of Windows or Office use it, or can I
uninstall it? )
