Challenges with Node-Locked License in Win 10

      Hi, I have been issued a license by Ansys in a file called 'LSTC_winlic.txt' which I have tried to use without success. It appears to give access to MPPDYNA (Option: Revision 13), MPPDYNA_971 (Option: Revision 6), MPPDYNA_970, MPPDYNA_960, LS-DYNA (Option: Revision 13), LS-DYNA_971 (Option: Revision 6), LS-DYNA_970, and LS-DYNA_960. It lists a key at the bottom and at the top it lists 40-digit SERVER and additional 'Interfaces'. I have tried unsuccessfully to run LS-DYNA of various versions (the key appears to let me use MPP or SMP versions 13 or 6 so I have been trying 13 smp and mpp, but also 12). I have tried running it both from LS-RUN after loading in the license, and from the command line after checking that the two environment variables point to the local license. However I always get the same 'Error Bad license keys!' message in my output/log. I must be missing something? Below is an example output. 

      Thanks,

      Will Grissom

      Hello,

      We do not issue node locked licenses anymore; we only issue network licenses. Please set the following environment variable on the client machine:

      LSTC_LICENSE=network

      Also, the "Bad license keys" error is usually caused by one of the following:

      1. The license file was modified. The LSTC license file cannot be modified (change the text, etc.) or else the bad license key error will show up. Please use the original LSTC license file that was sent to you.
      2. You are using an older version of the LSTC license manager. The solution is to upgrade to the latest:

      https://ftp.lstc.com/user/Download-Instructions/Job-License-Manager/

      username: user

      password: computer

       

      Here is the LSTC license manager installation procedure for Windows:

      https://ftp.lstc.com/user/license/License-Manager/LS-DYNA%20Win%20License%20Server%20installation%20and%20update%20Aug%2026_2.pdf

      Here it is for Linux:

      https://ftp.lstc.com/user/download-instructions/License-Manager/LSTC_LicenseManager-InstallationGuide.pdf

       

      Finally, the following website will have most of the LS-DYNA resources:

      https://lsdyna.ansys.com/

       

      Let me know how it goes.

       

      Reno.
