This guide assumes you have installed ESM 6.3.1.0 and JDM 6.2.1.4 separately.
**NOTE** This method does not work on Windows 8, to overcome the errors you see in Windows 8 you must copy the contents of the JDM directory into your ESM directory and overwrite all duplicates. This means that you do not have to follow this guide, but it also means you cannot then select between the bundled JDM and JDM 6.2.1.4 as you have overwritten the original bundled JDM.
So start up ESM and login to the program.
From the top tabs, select "Edit" then "Preferences..."
A new window will open
On the bottom right part of the new window you will see a group called "Override Default".
As the radio button already has "JDM" selected in the "Select Choice:" section, click on the "Use Other location" radio button in the "Select JDM:" section. You can now manually type in the path in the "Select Path:" box or you can click on "..." and browse to where you have installed JDM 6.2.1.4 (C:\Nortel\JDM) in this example
Click "Ok"
And thats it! Now when you double click on a device on a ESM topology map (or right click, Device Manager) ESM will now launch the newer version of JDM and not the version bundled.
Please leave a comment if you have any questions or if you have found this guide to be useful. I will attempt to get back to you in a timely manner.
