Frank's last sentence explains what will happen in some
organizations, no matter how the OSGeo4W 'installer'
is created.
Where I work, any product that is going to be installed
on 'more than a few' workstations has to be "packaged".
If the vendor's software (e.g. OSGeo4W) is provided as
a "setup.exe", then that will be 'exploded', and the
component parts (files, registry settings, shortcuts, etc)
are all included in an MSI file.
If the vendor supplies their software in an MSI, then we
never modify that MSI, but will always add an MST (a file
that is used during the installation to Transform the MSI).
Our MST might simply add properties to control how the
installation takes place (e.g. suppress all user interaction),
or it might be 'more intrusive', to the point of not installing
parts of the vendor's software package.
As for the flexibility of using an MSI, they can be very
flexible, so I'm not sure what limitations were encountered
in regards to OSGeo4W. They can likely be overcome, however,
like anything else, it may take some time/effort, and the
choice might be to spend that time/effort on other things.
