[wix-users] Calling DLL Interfaces from Wix

[Edwin Castro]

You don't call any dll interface from WiX! You write one or more functions
in a custom action dll that load and call the other dll. In WiX you author
the CustomAction and schedule it to run in InstallExecuteSequence.

See
http://wixtoolset.org/documentation/manual/v3/wixdev/extensions/authoring_custom_actions.html
for an example of how to do the authoring of the CustomAction in WiX.

See
https://docs.microsoft.com/en-us/windows/desktop/msi/dynamic-link-libraries
for details on authoring the customaction dll function(s).

NOTE: Locating/loading the "install driver" dll from the customaction dll
might prove difficult or impossible. I'd recommend you find a way to
combine both dlls into one dll if at all possible!
