You should be able to find your instance information by using the Configuration Manager utility. Under Explorer Tools, you should see a sub-heading for ICM Instance Explorer.

You can also find it on any existing ICM server using Regedit:

HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems, Inc.\ICM\\CurrentVersion\InstanceNumber

Do note that if you are adding new PGs into a 7.x environment that the setup will collect the instance information from the Domain Controller, and provide you with a drop down list to select from.
