I posted this in the wrong discussion group earlier so I'm sorry to any one who got stuck reading it twice... But maybe I'll find an answer here :) This is probably a dumb question but I can't seem to find an answer and this is my first dealings with FlexLM/ACAD. We've purchased upgrades for the Inventor series. I don't know what needs to be changed (if anything) for the FlexLM licensing to work. I haven't installed the upgrades yet or altered the license manager in any way. Thought I'd do a little research first... Can I just install the upgrade at the end users and everything work ok? Or do I need to change something in the license manager? The invoice I got came with new serial numbers so I wasn't sure what to do with those either.. Any info is greatly appreciated! Thanks
