EDI Email folder inside of the BRO folder

This document is designed if you have attempted to install Mastercom for the first time OR if you are doing an update, and the update to Mastercom was not saved to the root of the drive thus installing in the wrong location.  Lets begin.

Our example for these instructions is that Power Broker is installed on the P: drive.  If you use any other drive letter, please supplement the P: in this document to the drive letter you use.

You have a P:\Email and an P:\BRO\Email

 This means Mastercom is installed inside of Power Broker.

 Go to Start, All programs, Mastercom, Settings Main.

 Take a picture of this screen with your phone or create a screen capture.

*** If your Settings MAIN screen is missing your PRODUCT I.D., you will need to contact tech support before doing these steps***

 Close this window, then go to start, control panel, programs and features, and uninstall all of the Mastercoms and Juniper software.


Go to Start, control panel, system, advanced system settings, environment variables, change all MV to MV=P:\Email


 Open Windows Explorer and look for P:\Email and an P:\BRO\Email or if you have a third or fourth \Email folder, rename all of them to \EmailOld.

 Go to this link and download setup.exe to the ROOT of P


Open a CMD window by going to Start Search/Run and type CMD

 Type P: and enter

Now you are at the root of P: so type setup.exe

Ensure the installation points to P:\Email in the install screens both times.

The phone picture/screen capture will have all of the details required to fill in the spaces provided.

 7-Zip install would go to P:\Email\7-zip folder


Go to Start, All Programs Mastercom Settings Main

Type in what you had from your phone picture or screen capture.

Save , and exit Mastercom.  Log into Power Broker and go to EDI, Send and Receive and then hit proceed.

This should test your EDI connection.
