Best way to figure out if the FlexNet agent used to be installed on a machine?

Specifically talking about Windows machines, and primarily servers here. Is there a good way to see if a server used to have the FlexNet agent installed, on a machine that does not currently have it installed?

I forgot to add that I have found some evidence of this on the History tab in the Inventory Device Properties, but not sure if that's a reliable source/if there's a better way.

Not sure if there's a truly reliable way, but there should be plenty of things indicating former agent installations.

• On the machine itself (Registry, file system, services, log files)
• In the InventoryDB (tables Computer & InventoryReport) or perhaps if you have replication enabled
• As mentioned by you, in the WebUI history
• The ComplianceHistory table might even hold data for inventories no longer shown in the WebUI
