When you say you’ve replaced InstallShield with the WiX
toolset, what version of InstallShield did you replace? I ask because the
non-MSI versions of InstallShield used a scripting engine to do the
install. That engine (as I’ve been told) doesn’t do nearly
the same amount of integrity checking that the Windows Installer does. For example, the Windows Installer maintains a rollback script of
all the files that were replaced during the installation. Thus, if the
user cancels, everything gets put back the way it was. That adds overhead
that most installation technologies don’t implement (and one of the
reasons I cringe every time I see another product released on those engines). Now, if you were using InstallShield for Windows Installer and the
package you created with the WiX toolset was slower... well, then the WiX
toolset probably has a bug. <smile/> From:

[mailto:[EMAIL PROTECTED] On Behalf Of Simon
Topley Good morning to the Brotherhood/Sisterhood,
I'm sure this is a problem others have
encounted. I have now replace our suite of installsheild products with spanky
new WIX versions. I have managed to elimitnate a large amount of redundant code
(previous installers copied large amounts of file that were never used). Most
of the installers are now half the size in compressed form. Dispite this the
installation process now takes longer (so I'm told, I intend to run some
performance tests later today). Is there a standard explaination for this that
I can give to people (i.e. talk to city hall) I am playing with the idea of having internal
versions (products that will only be used by testers and support staff) as
uncompressed in the hope that most of the time is being spent extracting files.
