About the tool

The utility will only look up information relevant to troubleshooting installation and license management problems, and will not collect any other information from the PC in question. It will write the result to a file which is in human readable form. Thus can you see and study the contents before sending the information to IAR Systems.


Download the tool from the link: IAR License Diagnostic tool.zip.

Run the "licdiag" utility

  • Un-zip the archive. The licdiag.exe file is un-ziped.
  • Run the utility from the command line. It will create a file named IAR_diagnostics.txt in the folder where licdiag.exe is stored. (If running the utility by double clicking it from the Explorer, there may be cases where the file is created in another directory. That's why it should be run from the command line.)

It is perfectly okay to run this application several times. If the file IAR_diagnostics.txt already exists, it will append the new information to the file.

Additional log file

There is one more file that needs to be sent to support. It is the file named lms.log. The file is found in the directory of : ...\Program Files\Common Files\IAR Systems\License

Send these two files to IAR Support

  • The IAR_diagnostics.txt generated by this tool.
  • The lms.log file generated by installations etc.
