My license for version 16 has expired.
I received a license file for version 17 from our IT department (JMP170_9CZ949_70252549_Win_X64).
My question is how do I download the installation file of version 17?
Get in touch with your IT department and ask for the JMP 17 installer (software depot).
Otherwise open a support case (support@jmp.com). Support can provide you more details about the correct software/download order.
This might give some idea how to get the installation file JMP 17 Deployment Guide (Windows) (I assume you have Windows).
If this doesn't work, you can find more information from JMP Support page (also contains deployment guide for macOS)
