Robert Bull Just installed azzCardfile 4.1.08, 2011.11.19, the latest at the time of writing. I've installed it over an older copy that had the errors, and had to be manually set to work properly, per the blog post. The new version seems to install correctly on Vista Home Premium with UAC On, picks up its registration details, etc., no errors. It insists on its own data folder "\MyUserName\Documents\azzCardfile Files". My manually-corrected older version was pointed at a different but similar directory, so I've moved the files across and everything seems to be OK.
