I am currently wiping my ENTIRE hardrive and reinstalling Windows on my (currently very slow) laptop. However, I don't want to lose my expensive version of Mathematica, and it looks like Wolfram is very strict about "new" devices. Will reinstalling my license give me problems?

  • $\begingroup$ Depending on what sort of license you have, the following may reveal the location of your license file: SystemOpen@FileNameJoin[{$UserBaseDirectory, "Licensing"}]. Back it up and restore it. Then it will probably work unless your hardware has also changed. $\endgroup$ – Szabolcs Jun 30 '16 at 17:52
