I would like to identify Studio installations so my plugin recognizes that it runs on several installations, on different PCs. One possibility would be to use some hardware identifier (or their combinations) but according to various resources, it is not very reliable. One option would be to get the licence number even though I guess there are licences for multiple installations on multiple PCs (and such possibility could be misused by API developers :). Does API contain some installation-specific attribute / identifier / string? If not, what would you recommend to use?
