Installing MAPI gateway

[VinceWhirlwind]

I think these are the latest instructions for setting up the MAPI gateway:
http://edocs.mitel.com/UG/Apps-Solutions/MiCollab%207.1/MiCollab/mac/np/4_unified_messaging/install_mapi_gateway.htm
 
It says:
 
Insert NuPoint UM Software DVD1 into the server's CD/DVD drive. (This is the same DVD that you used to originally install NuPoint UM.) 
Locate and then double-click the MAPI GW executable file (MAPIGatewayInstaller.exe).
 
But our NuPoint came as part of MiCOllab, which was installed using a vMAS .ova file.
 
Does anybody know where to download MAPIGatewayInstaller.exe from?
