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 8 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.

Optional Third Party Open Source Software for Programmers
Igor Pro uses open source third-party libraries for which we are required to provide the source code. It is never necessary to download this source code. Interested users should see our Open Source page.
The files listed on this page are the most recently build version of Igor Pro 8 for each supported platform.
You should only use one of the files here if you have been pointed to this page by WaveMetrics or if you have discovered a bug in the latest official release of Igor Pro and wish to see if it has been fixed by WaveMetrics already.
Updates for other programs from WaveMetrics (including the Japanese version of Igor) may be found on our main web site here.
