View Full Version : Merge Modules

10-26-2005, 06:24 AM
A very quick question....

The redistributable merge modules for MDAC, JET, etc .... Do I need to create a custom action to install them (to determine if the version on the client pc is older for example), or will Installshield do that itself?

Most (almost 99% which I have used) of the Merge Module works by including them directly into the project, but I would prefer to go thru the documentation (if available) if they are platform specific or some condition need to be put on them (generally, Not!).

As for the one provided by Microsoft, the logic is built inside them which I belive will take care of everything. But....read the docs !

Some MSMs can be configured, usually a property is documented. For instance, the old MSDE MSM had a property with a password for the database server.
Usually they are self-contained, including system requirement checks, install, uninstall, rollback, reboot-enforcing etc.
