Not to hijack this old thread, but I have a related question within this topic. I have AutoCad 2013, standalone with a permanent license running just fine under Windows 7 64-bit. With the Windows 7 end-of-life looming, I'll need to do something before 2020.
Before I attempt to go to Windows 10, I'll play it safe and buy a couple of years with Windows 8.1. I know that I need to apply SP2 to AutoCad 2013 to run 8.1, so I'll do that. I plan to do an in-place OS upgrade on my workstation to go from Windows 7 to 8.1 ... can I do that directly without worries, or should I use the "License Transfer Utility" applied to AutoCad during the OS upgrade? Again, I'll not be moving to a different workstation, but simply upgrading the OS on the same workstation. Some of the support info suggests using the "License Transfer Utility" during an OS upgrade, but it is not clear if it is really necessary.
Any real-world experience or recommendations on this issue? Thanks much!
