From a professional stand point: it is absolutely incomprehensible that a company like LM does not want to disclose (not even towards its professional licensees) the information which PC system (eg. brand, type, etc) their are using to verify - annex certify - their product on so it is working correctly as intended for its customers (or at least at what settings). Sadly I have seen this happening at other software companies too...
I think a community like this would gratefully benefit from this simple information (left alone the many that like to have/tweak their own system built and use add-ons). At least, you have a proper concrete reference then...
A great deal of fellow members here would rather be using the product than trying to get it run (properly) ;-), no?
