Each purchase is a single "concurrent license", which allows you to install as many copies as you need for 1 simultaneous user. For example on your work, home and laptop computers, or when you change computers or re-install your OS.
After each new install you will be asked to copy and paste in your purchase serial number. You must be connected to the internet for this validation step.
Texture images, morph targets and FaceGen '.fg' files created with Artist are yours to distribute.
