### Login

Login to the Theia Software Downloads [portal](https://service.theiaserver.com/login) using the login credentials provided to you in our welcome email.

* Download the Theia3D application installer.
*  If available, download the Graphics Card Engines for your GPU. 

{% hint style="info" %}
**Note:** If none are available for your GPU, they will be built automatically the first time Theia3D is run.
{% endhint %}

* Copy your license key for safekeeping offline.
  {% endstep %}

{% step %}

### Drivers

Check that your [NVIDIA graphics card drivers](https://www.nvidia.com/download/index.aspx) are up-to-date. If not, download and install the latest drivers from NVIDIA.
{% endstep %}

{% step %}

### Run Theia3D

Run the Theia3D application installer and follow the instructions

* You must scroll to the bottom of the EULA to accept it.
* If you downloaded a Graphics Card Engine from the Theia Software Downloads portal, run the executable once the Theia3D application installer has finished.
  {% endstep %}

{% step %}

### Launch Theia3D for the first time.

* When prompted, enter your license key to activate the software.
* If a Graphics Card Engine was not available for your GPU from the Theia Software Downloads portal, they will be built automatically at this stage. This can take several (\~30) minutes, but is only required the first time Theia3D is opened.
  {% endstep %}
