If you directly open the license file(.xml) and modify the content, the license file will no longer work. In this case, please fill out this form to apply for a free student license again.
If you have trouble setting up the license file, please try this step:
- Close Astah UML.
- Save your student license file (.xml) directly in the Astah UML installation folder.
- Start Astah UML.
- Then your license file should be installed.
