## 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.
