Updating Maintenance Licenses

When you renew your maintenance, we send you a new license file. This file will enable future versions of SIMetrix up until the time when your maintenance expires. That way you only need a new license once a year, not every time a new version is released.

Below we explain how to install the new license when you receive it

Important Note

You receive a new license when maintenance is renewed to enable future versions. If you choose not to renew your maintenance, your old license will continue to work with your existing SIMetrix or SIMetrix/SIMPLIS version. Except in exceptional circumstances, we always issue non-expiring licenses.

Installing License

Installing Standalone and Portable Licenses

You must be logged in with administrator privilege to install licenses. If you are using Windows Vista and have "User Access Control" enabled you must start SIMetrix in Administrator mode by right clicking the SIMetrix icon and selecting "Run as Administrator"

  1. Start SIMetrix then select menu Help | Reinstall License.... OK message box.
  2. Restart SIMetrix
  3. Select Standalone or Portable when asked for the license type. Press Close
  4. Press Install License...
  5. Locate the license we sent you on your system. Press Open to accept file
  6. Press Close
  7. SIMetrix should now start normally

You will not need to repeat this procedure until your maintenance is next renewed.

Installing Network Licenses

  1. Copy the license file we sent you to the directory where FLEXlm is installed. Important: You may need to edit the license file to enter the server name. Open the license file in a text editor such as notepad and look for the line that starts "SERVER". If this is followed by "enter_server_name_here" then replace "enter_server_name_here" with the actual server name then save and close.
  2. Move or delete the existing SIMetrix license file. (All licenses issued for v4 or later have a .LIC extension)
  3. You must now tell the license server to re read the license. On Windows we recommend that you do this by shutting down the license server and restarting it. This can be done from the Windows control panel. On W2K/XP open control panel then go to Administrator Tools -> Services then locate the SIMetrix FLEXlm license server. Select and right click to stop then start again.

    You can also use the lmreread facility. We have found this to be unreliable on Windows, but works OK with Linux. The syntax is:

    lmutil lmreread -c licfile -all

    where licfile is the path to your license file.
