Mnova Installation


This article describes how to install Mnova, an application for electronic and vibrational spectroscopic techniques.


UNH has a site license for the Mestrelab Research Mnova application that allows for 150 active users. Under this license, all students, faculty, and staff may use the Mnova software on UNH-owned or personally-owned computers for teaching and research purposes.

The instructions below are for students or faculty/staff who would like to install Mnova on their own computer.

System Requirements

Your computer meet the following requirements to use Mnova:

  • Windows 7 or newer; macOS 10.7 or newer; Linux (many versions - see download page)
  • 1 G RAM
  • 2 G available hard disk space 


To obtain and install the software:

  1. Go to
  2. Use the large buttons to find the appropriate copy of Mnova for your specific operating system.  We recommend you download the most recent release unless you have a specific reason otherwise.
  3. Click on the desired version to download the installation files to your computer.
  4. Proceed through the installation process:
    • For Mac, just drag the program to your applications folder.
    • For Windows, proceed through the installer, accepting the license agreement and most defaults. When at the Custom Setup stage, only install the MestReNova Framework and the NMR Plugin.  Do not include any of the other plugins.


The Mnova software requires a license file to activate.  The activation is through October 2019.  If you continue to use the program after that point, you will need to repeat this process to obtain a new license file.

  1. Connect to the repository for the installation files from Box at This folder is accessible to all UNH account holders, but you may have to login with your UNH username and password to gain access.
  2. Open the folder for the Mnova software.
  3. Locate the license file for the version of Mnova you have installed.  For most users, this will be the University of New Hampshire Campus NMR v1.8.lic file.
  4. Download the correct file to your computer. You can do so by clicking on the file name to display the file, and then click the button in the upper right. Be sure to save the file to a convenient location such as your Downloads folder or Desktop.
  5.  Start the Mnova software on your computer.  When it first runs, you will be prompted to install the license file.  Click the Install button.
  6. Navigate to the location where you saved the license file and select it in the file browser dialog.
  7. After you receive notice that the license file was accepted, you may need to restart Mnova to get it fully activated.

Using Mnova

Once you have completed the installation, you can run Mnova by using the MestReNova shortcuts in the Windows start menu or on macOS by finding the MestReNova item in the Applications folder. Mnova is installed entirely on your local computer, and you do not need to be connected to UNH's network to run the program.  The license activation, though, does need to check into our central license server every 90 days to stay active.  If you receive a notice about your license not being active, connect to UNH's network and try again.
