Hi,
The MergeMod.dll is a part of Visual Studio and it is used for merging at build time.
Microsoft Platform SDK states: "Mergemod.dll provides a COM object that implements merge operations and source image generation for merge modules".
So you don't need to have it on the target machine when the package is installed.
Regards,
Gigi
