IDL software is licensed and paid for by specific research groups within the department. If you are not a member of these groups, then please do not try installing this software.

• Download the IDL CD image (idl64win.iso) from our software downloads web page: https://www.physics.umn.edu/resources/computing/download/index.html (requires authentication).
• Burn a copy of the CD, and run the appropriate Windows installer (usually this will be setup32.exe)
• Next you need to define an environment variable to tell IDL the location of our license server.
  • Open the System control panel.
  • Click the Advanced tab, and click the Environment Variables button. Click the New button below the System Variables box and enter the following information:
    • In the Variable Name field, type LM_LICENSE_FILE in uppercase letters.
    • In the Variable Value field, enter 1700@idl.spa.umn.edu
  • If LM_LICENSE_FILE has already been defined for another software product, the definition of this license file can be appended using a semi-colon (;) as the delimiter. For example: C:\License\mylicense.dat;1700@idl.spa.umn.edu
  • Save the settings.

(Note, the IDL license server is only available within Tate Lab).
