Adobe AIR 1.5 Update success unclear

Question

After installing the Adobe AIR 1.5 Update for Fireworks CS4
on my Mac OS X 10.5.6 machine, the installed version of Fireworks
is still set at 10.0.0.495. This version string appears in the both
the About box and in the Finder Get Info window, despite the fact
that the installer window displayed that it was installing Adobe
Fireworks CS4 10.0.1.
How can I determine that the install worked?
As a sidenote, I find the entire installer to be very
non-intuitive to use for a Mac user: the installer does not use the
standard Mac install process, the installer is named "Setup.app"
with no indication what it is, the installer script is hard coded
to look for an application folder named "Adobe Fireworks CS4"
(which breaks if you've renamed the folder), the user is prompted
for a password before being told what it is doing, multiple
applications launch as part of the install process resulting in two
applications named Setup appearing in the Dock, the Quit option in
the application menu bar is greyed out and the quit button is
labelled "Exit". Things like this impact perceived quality of
product.

Answer 1

The update will not affect the splash screen or About Page
version number.
For a quick check you can try creating an AIR package or an
AIR preview. If everything works smooth then the installation would
have been a success.
The other details related to installation on a Mac should be
seen on all other Adobe app and not restricted to Fireworks alone.
