Download the fully-functional Igor Pro 9 and try it free for 30 days after installation. After 30 days, the Igor will lapse into limited functionality demo mode. The limitations of the demo mode are:

  • Saving is disabled.
  • The clipboard contents cannot be transferred to other programs.
  • The printing output is lightly over-printed with Igor-related words.

To avoid these limitations, purchase an Igor Pro license to restore the full functionality.
