Paul,
From the PixInsight FAQ page.
2.7 If I have to replace or format my hard disk, do I have to re-activate my license?
The PixInsight core application only asks for an online license activation if it can't find a valid license file. Your license file uniquely identifies you (the license holder) as a commercial PixInsight user. It is a very small file with the following name:
On Mac OS X and Windows:
pixinsight-license
On FreeBSD and Linux:
.pixinsight-license
and is located on your home directory (or home folder):
On Linux and FreeBSD:
/home/<user-name> or /usr/home/<user-name>
On Mac OS X:
/Users/<user-name>
On Windows Vista, Windows 7 and Windows 8:
C:\Users\<user-name>
where <user-name> is your actual user name on your operating system. If you simply copy your license file to the home directory of another machine you own, the commercial PixInsight application will run on that machine without problems. If you take the precaution to make a backup copy of your license file, then you'll never have to re-activate your license.
Alternatively, you can reactivate your license using our software distribution system. See FAQ 2.10 for details.
2.8 How can I install PixInsight on several machines?
You just have to copy your license file to your home directory on each machine; no license activation is required. Please read FAQ 2.7 for details.
Alternatively, you can reactivate your license using our software distribution system. See FAQ 2.10 for details.
