Miraplacid Publisher Installer Component
Miraplacid Publisher SDK Edition can be installed from special Installer Component.
This is self-extracting DLL file which can be used from external setup utility.
This file is not present in the package; it could be generated with special utility,
Setup Maker.
Installer component exposes two kind of interfaces: DLL exported funstions (API) and COM interface.
COM interface allows extenal program to have detailed information about installation process.
COM parameters are: coclass MPSsetup (Miraplacid.MPSetup {12727FEB-6A92-4F41-928F-752A30531987}).
It contains two interfaces: IMPSetup {CFA1603C-D60A-4896-B46F-FD4BF02921F8}, the main interface, and
connection point interface _IMPSetupEvents {A5ECAD06-CCB6-426D-9905-93EA347EE989} for installation events from Installer component
to external software.
Examples of setup utility are located at examples.vb\setupui and examples.net\MP_SE_Setup folders at this package.
Important note: If you will use installer component from your
.Net setup program, please, do not forget to build it as a 32-bit executable,
if your installation application will register dll server itself. Or, it may call system application "regsvr32 mpublisher.dll" to register mtd.dll server.
