You can download JMP by going to www.sitelicensed.iastate.edu/software/ You should be able to directly download an install JMP from there. You will have to type in your ISU netid and password in order to do this. Once the file is downloaded to your desktop (it is a pretty big file at 271 MB) run the Initialize.exe and follow the step-by-step instructions. When you come to the option to Modify, Repair or Remove, select Repair. The installation program should do the rest.

  Clicking on the .JMP file should open up JMP with the data in the data file. You will not have access to the JMP Starter menu if you open JMP in this way. However, you can get the JMP Starter menu by going to View on the main menu for JMP. If you are using a Mac or if the file otherwise does not open in JMP you will have to save the file to your desktop, or elsewhere, first. To do this Right + Click on the link this should pop up a menu that allows you to save the file associated with the link.
