If you can skip if the SAME version is installed why can't you skip if a
NEWER version is installed?

Because it is not possible to query a newer version reliably.
Especially, detecting yet to be released newer versions seems to be
difficult to me. The MsiQueryProductState call can be used only if the
product code of the package is known.

We skip the same version if it is installed, because that code is
there, otherwise probably we would not bother. However, we don't
detect the same version of localized VC++ redist packages. Check is
only against the product code of en-US version.

My opinion is that it is better to always install vcredist, because it
is the safest, and it makes no harm, if a newer version is installed
already. Maybe we should use the /QN switch instead of /QB so most
people would not notice it and would not complain about it. :)
