First time using IIA so maybe I did something wrong but IIA, it seems, will run only once. I downloaded IIA and ran it to become familiar with the screens and options. I left all the asset and support fields blank. In fact, I don't think I changed anything since I was just reviewing the utility. Now that I want to update the fields with the correct values, IIA won't run. Is it a one-time per machine utility? Once a machine is registered (Microsoft Windows) does that stop further updates with IIA? How do I update the support fields?
