Error : FLEXlm version of vendor daemon is too old - Error : FLEXlm version of vendor daemon is too old Description In the Questa* FPGA Edition simulator and Questa* FPGA Starter Edition simulator version 2024.1, you might see this error or the following error if you are using the MGCLD daemon v11.16.4 “Unable to checkout a license. Make sure your license file environment variable (SALT_LICENSE_SERVER, MGLS_LICENSE_FILE, LM_LICENSE_FILE) is set correctly” Resolution To avoid this error, upgrade to the Siemens* Flexlm (SALTD) daemon v11.19.5 Download the daemon from the download page There is a change to the Siemens* License in v11.19.5.0. If you’re running a floating license server for Siemens* licenses, manually change the VENDOR daemon line in the license file from mgcld to saltd, for example: VENDOR saltd <path to saltd> Note: Do not change any of the INCREMENT lines. Leave the INCREMENT lines with the original vendor daemon name (mgcld).
