# Trial By default a trial license valid for 30 calendar days will be installed and used when Invantive Bridge is installed. The user will receive a license error message after 30 days or when the data container was previously used with a trial license. # Permanent License The recommended steps to install a license key are: - Place the text of the license key in a file named 'invantive.lic' in the folder %USERPROFILE%\invantive. - Or set the environment variable `INVANTIVE_LICENSE_FILE_PATH` to the full path of the file. - Restart Microsoft Power BI. Alternatively, the file path of the license file can also be specified using the connection string key "license-file" of the Power BI data source as in: license-file=h:\invantive\invantive-bridge-license.txt Other driver-specific configuration options such as the client ID or number of parallel requests (requests-parallel-max) can be configured in the connection string too. The available options are listed with the data model of each Invantive SQL connector on [https://documentation.invantive.com](<%LINK_CAPTION%>).
