Diamond also has a license debugger feature. A "License checkout failed" pop-up appears if the license file cannot be read when starting Diamond. In the "License Debug" tab of the License Debugger that launches when you click the OK button, you'll see the expected and found strings (no matches if no license found). The "License Information" tab shows the referenced license file name and directory as listed in the Windows environment variables. With this information, you can easily determine if the directory (or environment variable) where the license file is located is correct, or if the contents of the license file are what you expected. You can also browse and specify the location of the license file, which can help you troubleshoot.

If this does not solve the problem, please check again if the license type (Node-lock or Floating) was selected correctly when installing Diamond.
