Latest Igor Pro Installers

Igor Pro is an interactive software environment for experimentation with scientific and engineering data and for the production of publication-quality graphs and page layouts. Igor has been used by tens of thousands of technical professionals since its introduction in 1989.

Download the fully-functional Igor Pro 7 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. If, within 90 days of purchase, you are unsatisified in any way you can delete Igor Pro from your computer and we'll refund your money, no questions asked.
