It seems that Autodesk invests so little in securing their own product that, in order to combat piracy, their license agreement includes a section in which you grant them access to all your network machines (and beyond one assumes) and any contained files and information just so that you can prove to them your are not a thief and are using this software legitimately. This having already suffered the ludicrously high price to pay for it in the first place!.Get a grip Autodesk. There are many ways to use machine level authentication without accusing all your customers of being software pirates until such time as they can prove to you, after downloading and installing your own scanning software, that they are not!!Hugely outdated process and an unnecessary intrusion in to what could be (and is in my case) commercially sensitive data. As this review is for Autodesk and not the AutoCAD product, I can only comment on that.
