It may happen that you get a warning that the program has been blocked by the security parameters due to an attempt to execute a self-signed program.
This can sometimes be fixed by adding IRIT to Java's security exception list:
- * Windows: Start menu > Java > Configure Java > Security tab;
- * OsX: System parameters > Java > Security tab;
- Then for both click on the "Edit Site List" button;
- and add the URL http://www.irit.fr
If it does not work, please download executable LoTREC.
