## 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.
