Last night the hard disk on my laptop decided to crash on me. Since I will have to replace this hard drive I will obviously need to reinstall all the software that used to reside on it, including Pixinsight.
Luckily I had PI installed on both my laptop and my desktop computers. Therefore, I still have a copy of my commercial license key.
My question is: Please describe, step by step, the proper way to reinstall PI on the new hard drive once I get my laptop back from repair.
