And you anti-virus application is...?

Of course, I did thoroughly check my system for viruses after the "update"
first failed about a week ago. The system is clean.

Also, I have several versions of Flash & ActiveX off-line installers, and
they now all fail with the same error (an OSX file fails to register, the
actual file depends on the version), even when anti-virus is disabled. I was
able to install them as needed before without problems.
