I think a perfect scenario for using instances is when you have a single
product that must be installed independently for individual clients. So
lets say I have a web project consisting of a web service. This project
will have its own web.config, global.asax, etc. The docs state that sharing
components among multi-instance is not supported so instead of being able to
build a single.dll and sharing it among multiple clients, I have to copy
that .dll over and over. But I digress.
The idea is that since there are individual configs for each client, I need
to have each instance of the project running in its own web application and
I have yet to find a way to get Wix to do this. I've read about instance
transforms, but from my understanding, wix really doesnt support multiple
instances. I know SQL Server 2005 uses wix to manage multi-instance, but
SQL Server 2005 is only getting installed a single time and the instance
transform is making mods to the installed application.
It gets quite a bit more complicated when you have individual products (that
are mostly identical) yet are not the same single install. Modifying and
removing individual sites with this approach seems daunting at best. The
matter is also complicated by the fact that instances are basically nested
under the initial install inside the registry and I haven't been able to
determine the ramifications, lets say, if I remove the initial install
instance after adding additional instances. Just feels dangerous to try to
use Wix in this manner.
I like the ability to run via GUI or script, but in this scenario, Wix is
making me nervous.
