If you have a failed system motherboard or hard drive, you risk loss of the softkey. See the backup instructions below to prepare for potential hard drive failure. However, if you need a single component such as video card, memory, CD drive, or wireless card replaced, this will not cause a problem with your Zemax license. Also, changing USB and other external devices will not affect the license.
Tips:
To avoid losing your license, you may transfer your license to another computer before replacing hardwar or cloning your hard drive. Follow the guide on this page. Transfer it back after the computer is working again. If you are using versions of the software after August 2016, you don’t need to complete the transfer onto a second computer.

Windows 8 and 10 also offer a “Refresh” or “Reset” option to repair the operating system, which is similar to wiping your hard drive and reinstalling (but does not require a CD / USB boot disk).
