How do I know which version I have?

If you are able to launch the program:

First, you can find the full Prism version number on the Welcome dialog, right under the Prism logo. 

You can also find it in the About GraphPad Prism dialog:

  1. Run the program.
  2. Open the Help menu (Windows) or Prism menu (macOS).
  3. Choose About Prism.
  4. You'll see the full version number on the dialog.

These commands are standard, so work with all software.

Starting with Prism 8, Windows and Mac versions of GraphPad programs have three digits - MAJOR.MINOR.PATCH (e.g. 8.2.0) and only use numbers. Each version incorporates a Build number (e.g. 435) which is different across platforms. Earlier versions of GraphPad programs have two digits after the decimal place, for example Prism 6.02. Mac versions have a digit and letter after the decimal point, for example InStat 3.0b.

If you cannot run the program. 

If the program is not running, you can still get the version information from the program file itself.

On Windows, find the executable, i.e. prism.exe, right-click and choose Properties

On Mac, find the application file, control-click the Prism icon and choose Get Info.
