Cause

This is caused by a bug in the Inventory Beacon software whereby a connection to FNMP must be configured before you can add a Data Source, even if the FNMP test connection fails.

Resolution

This has been filed as bug PA 79662 - Bug in IB when configuring Data Source in Disconnected Mode

Workaround

To workaroud this, the procedure should be as follows:

Install the Inventory Beacon software (and any Patches/Service Packs)
Manually copy the %ProgramData%\Flexera Software\Compliance\ImportProcedures\ from the FNMP Admin Server to the Inventory Beacon
Open the Inventory Beacon application
On the 'FlexNet Manager Platform' tab, make sure the 'Enable connections to FNMP' box is ticked
Enter some connection details (URL, Username & Password), test the connection, and even if the connection fails, save the settings
Un-tick the 'Enable connections to FNMP' box and again save the settings (to put the IB back in Disconnected Mode)
Navigate to the 'Inventory Systems' tab
You should now be able to add a new Data Source by clicking 'New'
