On Windows, the 64-bit application is located within the Igor Pro 8 Folder\IgorBinaries_圆4 directory. We recommend that you use the 64-bit application (Igor64.exe) if possible.

It is also slightly faster than the 32-bit application. The 64-bit application will allow Igor to use more system memory, which means you can create, open, and manipulate larger data sets. 64-bit Applications (Windows)Īfter installing Igor 8, both a 32-bit application (Igor.exe) and a 64-bit application (Igor64.exe) will be available for use. Igor Pro 8 is supported on Windows 7 or later. See Activating More Extensions for details. All XOPs that ship with Igor Pro on Macintosh are 64-bit. If you need to use 32-bit only XOPs on Macintosh, you must use Igor 7. This means that you must use 64-bit XOPs with Igor 8. On Macintosh, starting with version 8, Igor Pro is a 64-bit application only. The easiest solution for this is to launch the Igor you wish to use and then double-click the experiment. If you have more than one copy of Igor on your hard disk, you will not know which version the Finder will launch when you double-click an Igor experiment. You can have Igor 8 and previous versions of Igor installed on your computer at the same time. To install, drag the Igor Pro 8 Folder to your Applications folder.

If you have an existing "Igor Pro 8 Folder" on the disk you'll be installing to, either remove or rename the folder to avoid overwriting the existing Igor files. macOS 10.15 (Catalina) is not currently supported. Igor Pro 8 is supported on macOS 10.10 to 10.14 (10.12 to 10.14 recommended).
