# Configuration settings

T4I configuration can be stored using two methods: in *registry* (preferred method) or *XML* file.

## Registry configuration

Configuration is stored in the key `HKEY_CURRENT_USER\Software\Holixa\T4I`.

If needed, this branch can be exported from the registry and provided to other users to import the T4I settings.

T4I settings can be imported to the registry by double-clicking on the exported file.

{% hint style="danger" %}
When editing the Registry, always proceed with extreme caution.
{% endhint %}

{% hint style="info" %}
Holixa T4I add-on restart is needed for the changes to take effect.
{% endhint %}

## XML file configuration

If an XML file should be used for the configuration of T4I, it is necessary to provide a path to the XML file containing the T4I configuration settings.

### Workflow overview for XML configuration file

1. If not already available, create a blank XML file (new empty file with XML file extension).
2. In the Configuration file name section, click the three-dots button.
3. Select the empty XML file.
4. The T4I configuration will be stored in the XML file selected.
5. The XML file can be redistributed and loaded on other workstations.
