After downloading and installing the OrCAD software, I am getting an error message that says, "license server... cannot be reached." 





There are several different issues that may cause this error message, for example: 

  • An error was made when you recorded and forwarded your Physical Address to EMA. 
  • The license server software needs to be refreshed by stopping and restarting the license server application using LMTools. 

If an error was made when you sent EMA your Physical Address:

EMA needs to rehost your license file (issue a new license) as license files are un-editable. This process may take up to 10 business days to for you to receive the EMA emailed and new license file. At that time you will be able to use the License Server Configuration Utility to reconfigure the Cadence License Manager so that it uses the new license. 


If you need to stop and restart the license server application:

  1. Open Windows File Explorer and navigate to “C:\Cadence\LicenseManager.”

  2. Double-click to open LMTools.exe.

  3. Open the Start/Stop/Reread tab.

  4. Click Stop Server. (If it says “Unable to Stop Server” that is fine, keep going).

  5. Wait at least five seconds. This step is crucial!

  6. Click the Start Server button.

  7. Attempt to open your software.


If you are still unable to open your software, forward the license.dat, debug.log, and .nfo files to EMA for additional troubleshooting:

  1. Open Windows File Explorer and navigate to C:\Cadence\LicenseManager.

  2. Copy and attach the “license.dat” file and  “debug.log” files to an email message addressed to EMA Technical Support:

  3. Create an .nfo file on your computer and also send it to EMA Technical Support. You can create the .nfo file by completing these steps:
    • Simultaneously press your keyboard Windows key and the R key.

    • Type “msinfo32” into the Open input field and press your keyboard Enter key.

    • Select the File > Save from menu and select a location where you can easily locate the .NFO file and attach it to your email message to EMA Technical Support.

EMA Technical Support will review the contents of the three files you are forwarding to them and determine the exact nature of your troubleshooting issue.
