InstallAware 2005 Studio by Bob Kelly |
Yes another MSI authoring tool, but this time one you may not have heard about- and one with a few gems wrapped in that make it worth taking a closer look. What sets InstallAware apart from the competition the most is how it goes about building an MSI. The graphical choices such as adding files and registry entries are provided as most tools offer. However, when you switch to the “script view” you do not see a list of sequences and actions, but an easy to read (and manipulate) script that spells out each action to be taken by the MSI and under what condition (see image at right). When everything is just as you wish, InstallAware builds a fully compliant Windows Installer setup requiring no scripting runtimes or distributable.
Installation
Being an MSI authoring tool itself, you may find yourself looking closely at the
installation of InstallAware itself- and without disappointment. The
installation dialogs look good and standing out was a Destination Folder dialog
that included a folder browse window, which is normally launched as a separate
dialog.
In an attempt to both take advantage of (and to show off) its cool Web Media Blocks
feature (click here for details-
it really is cool), the installation looks to the web to obtain certain features
and does not proceed if offline. When online, several plug-ins are downloaded
and, depending upon your bandwidth, it can take quite some time to complete. The
benefits of this feature are discussed later in this review, however seeing it
in action illustrates a potential downside: the installation took a very long
time to complete and the progress bar started over for each plug-in that was
downloaded. For the upside of this feature
click here to jump ahead.
To install InstallAware on a disconnected system, you either need the single
file installer (a 132mb version of the setup), or the web based installer
configured with the Minimum setup option (if you choose Minimum in the wizard,
it will automatically select only the features that are installable offline).

Interface
The
interface presented by InstallAware provides both a visual and script view of
your installation. The visual view (see image at right) parses your setup script and the other way
around, so that each is always up-to-date reflecting any change made. The visual
view contains 26 separate pages that represent different aspects of your
installation, from files being installed to your setup dialog designs.
Scripting
Not that any scripting is required, but definitely the most enticing
feature is InstallAware's scripting support. The unique scripting options still provide
full support for all Windows Installer standards: every setup that is generated
by InstallAware is in full compliance with all Windows Installer standards and
features. And it does so without any runtime/scripting requirements.
Anyone that has played with custom actions will know that there are many
limitations when trying to work with simple constructs such as an “else”
condition or loop. InstallAware aims to make MSI scripting behave as you wish it
did. To edit the parameters of a command, just double-click it. A dialog box
pops up with the options that are available for that command and if you wish
context sensitive help is available.
InstallAware does not take the approach of offering its own proprietary runtime
(as vendors such as InstallShield and Wise do) but instead offer what they refer
to as “Genuine Windows Installer Scripting”. One major benefit is you don’t need
to worry about pre-installation of a script interpreter and native support for
Windows Installer capabilities such as running with elevated privileges.
One limitation in this enhanced scripting functionality is that loops are not
supported when executing Windows Installer statements. While the InstallAware
script contains constructs that allow you to code loops, if you execute a
Windows Installer statement multiple times within a loop, only the last
iteration of that command will actually run on the target system. At any rate,
this is an inherent limitation of Windows Installer and is a situation you
should be able to easily avoid.

Dialog development
Using the dialog designer you can customize setup dialogs and design new ones
from scratch. InstallAware 2005 ships with a pre-built collection of twelve
setup themes. Having controls on your windows interact with one another is
fairly
easy: just double-click any control to bring up the Object Rules editor. This
editor lets you visually configure how controls respond to state changes of
other controls on the same window.
Plug-Ins
InstallAware ships with several pre-built plug-ins that perform various tasks,
and also includes two plug-in templates for plug-ins implemented using the
Visual C++ and Delphi programming languages. You may develop your own plug-ins
in any environment capable of creating standard Win32 DLLs.
Beyond developing your own plug-ins, some InstallAware licenses permit you to
redistribute the automation libraries, so you can build installers directly on
end-user systems as a feature of your own application.
Repackaging
InstallAware 2005 includes a new wizard called PackageAware. PackageAware is a standard before/after snapshot repackager that may be used to convert legacy
installations (that were built without InstallAware and/or Windows Installer technology)
to a Windows Installer installation. It works by scanning the system before and
after an application is installed. It then compares those two scans and
encapsulates the delta in an InstallAware installation project that you may
further customize as needed.
Web Media Blocks
The Web Media Blocks feature allows for web deployment and partial web
deployment. The latter option here is a unique one- InstallAware allows
splitting the data contained inside a setup package into multiple online and
offline parts. While web deployment traditionally involves putting the entire
setup online, this allows you to choose which parts of their setup are to be
downloaded, and which are to be provided with the main setup program. This can
obviously save time and bandwidth not only for end users installing the
applications, but also for companies hosting the downloads.
Compression
InstallAware 2005 includes a tool called the MSI CAB Decompressor, which you can
use to repack the installation databases provided as merge modules or
prerequisite MSIs by extracting the already compressed files and recompressing
them with InstallAware’s own enhanced compression algorithm (LZMA/BCJ2).
Patching
InstallAware 2005 introduces a “one-click patching feature”. To use one-click
patching, you need only include its latest set of files in your setup as before.
Then, add the installers for the previous versions of your package to your
project as Patch References. The created patches contain the absolute minimum
data and files that are required to upgrade your old versions to the newest
version. It accomplishes this by taking binary/differential scans of the files
in your different versions, and examining them. Only the changes between the
different versions are included in the patch.
If you take a look at an InstallAware MSI with another viewer/editor such as ORCA, you will see that each component is configured as its own conditional feature. The script sets properties to control the installation of items. It is this method that lets InstallAware perform some of its magic. However, keep in mind that if you are using other MSI tools such as Package Studio or AdminStudio in your environment, InstallAware packages may not be viewed normally (listing items feature by feature as they do). This could be an issue for those using conflict management tools or QA tools such as PackageCleaner which are confused by the complex nature of InstallAware packages. |
Error Free MSI Packages
Here is one claim I was a bit disappointed with. Having worked with
several other repackaging and authoring tools, I know it is almost a certainty
that they will not pass all ICE validation checks. The errors
encountered are most always acceptable and do not impact deployment, however
seeing so many errors in repackaged and vendor provided MSI packages starts you
thinking that creating one that passes certification without manual steps may be
impossible - unfortunately that assumption remains true.
InstallAware claims to create MSI packages that do not contain ICE errors, but
in my repackaged setup, I did find a several ICE errors (mostly warnings) including
5, 30, 40, 57, 60, 66, 82, 84. Most were just warnings and the resulting MSI functioned just fine, but the promise of an
"error-free package" was not delivered.
Shelling to other MSI files
A nice feature worth mention: when seen interactively, any shelled MSI setups
are
accounted for in the progress bar presented to the user.
Closing
In the end, InstallAware provides several powerful features found no place else.
Its intuitive scripting capabilities are unparalleled and the ability to host
infrequently needed features of your setup online alone makes it worth a closer
look. You can obtain a trial/evaluation version of InstallAware at:
