If you don't specify, WiX currently defaults to 1.0 ("100").
Very brief matrix:
MSI 1.x - basic MSI support, 32-bit only.
MSI 2.x - added 64-bit support.
MSI 3.0 - improved patching.
MSI 3.1 - improved external ui.
MSI 4.0 - Vista/2008 only. Incorporates
UAC-integration/restart-manager-integration/transaction-integration as well
as embedded-UI/msi-chaining and some improvements to patch support
(superseded components/patch removal custom actions.
MSI 4.5 - some bug fixes, and a redistributable containing the embedded ui,
msi chaining, and improved patch support (superseded components and patch
removal actions) for supported pre-Vista platforms. The restart manager,
UAC, and transaction integrations require platform support so they are not
in the downlevel redistributable (although they are retained in the
vista/2008 redistributable), but all the other improvements in 4.0 are in
4.5.
MSI 5.0 - Windows 7/2008 R2 only (AFAIK). Big things are SDDL for
configuring permissions, more control over services, finally some
improvement to the internal UI (a hyperlink control, a print and a
launch-app control events), along with a way to finally author packages that
can be switched between per-user and per-machine during the installation.
See the links off this page for more details:
http://msdn.microsoft.com/library/aa372796.aspx for details after 2.0.
This page details each released build from 2.0 on:
http://msdn.microsoft.com/library/aa371185.aspx.
MSDN no longer documents the changes that 2.0 added from 1.x apart from the
64-bit support, but no version of 1.x is supported anymore either (that was
much more than a decade ago). Most of the info on 1.x I found was on
Wikipedia.
If you look to see in the lists of what "wasn't supported" to determine
which version started supporting the things you use, you will then be able
to determine which is your minimum version. Or, if you have a minimum
platform (XP SP2, Vista, whatever) you can look to see what shipped with
that platform and avoid anything that isn't supported in that release of
Windows Installer.

Subject: [WiX-users] How to know which InstallerVersion to use?
I am a beginner to MSI and WiX and have a question on the InstallerVersion
attribute:
How to know what version of WindowsInstaller my .msi will need to run
correctly?
Is there some kind of table that I did not discover so far, containing all
WiX / MSI features plus the needed version number?
And, if I do not use the attribute at all, what will happen then?
Maybe this is a silly question, but I did not find any answer besides " For
64-bit Windows Installer packages, this property must be set to 200 or
greater.".
Thanks!
Markus
