View Full Version : Conditional installation of Merge Modules- SQL DMO

10-30-2003, 11:08 PM
Question 1: I am adding a SQL DMO merge module to the project. I want to only install this if there is no SQL Client present on the system. How can I do this?
Are the merge modules smart enough on their own, not to get installed when not required?

Question 2: If I upgrade my install with new files and run the setup again, does it install the SQL DMO again, or is it smart enough not to install it.

Question 3. If I run Add/Remove ( Remove), does it uninstall the SQL DMO?

It all depends on how the merge module is authored.

Usually, modules are intelligent enough to only install when needed, or when possible.

If you do an upgrade, and if the module hasn't changed, then those files shouldn't be reinstalled (though, it depends on the module).

Usually, uninstalling an app that uses modules that install a Microsoft technology do not uninstall the technology.

Thanks. You are right it depends on the author of the module.
