Install Advanced Designer on a Windows machine, then connect it to your ABBYY Vantage tenant. Any user can install Advanced Designer; some [additional installation options](/vantage/documentation/advanced-designer/additional-install) require administrative permissions. For hardware and OS requirements, see [System requirements](/vantage/documentation/advanced-designer/system-reqs).

## Install Advanced Designer

<Steps>
  <Step title="Download the installer">
    <VantageRegion>
      Download the latest version of Advanced Designer from [the Vantage download page](https://vantage-us.abbyy.com/ad/latest), which also lists the version, build number, and release date.
    </VantageRegion>
  </Step>

  <Step title="Run the installer">
    Open the downloaded file and follow the prompts to complete the installation.
  </Step>

  <Step title="Log in">
    Open Advanced Designer and sign in with the same login and password you use for ABBYY Vantage.
  </Step>
</Steps>

| Connect to a new Vantage instance | Choose **New Connection** from the **Show user profile** menu, then enter the URL, login, and password in the authentication dialog. |
| Switch between active connections | Select the URL from the **Show user profile** menu.                                                                                  |
| Close active connections          | Choose **Log Out**.                                                                                                                  |

<Note>
  If you try to connect to a Vantage instance with an incompatible Advanced Designer version, Advanced Designer displays a link inviting you to install a compatible version.
</Note>

## Language settings

To change the interface language, choose **Interface Language** from the **Show user profile** menu. Restart Advanced Designer for the change to take effect.

**Supported languages:** English, German, French, Spanish, Japanese, Korean, Chinese (Simplified).

## Update Advanced Designer

Advanced Designer checks for updates each time it launches. If a newer version is available, you'll see a notification with a link to the download page. After the application update, [upgrade existing skills to the newer Technology Core version](/vantage/documentation/advanced-designer/upgrading-to-new-version) to gain access to features added in later releases.

<Warning>
  Only one version of Advanced Designer can be installed on a machine by default. Installing a newer version uninstalls the existing version, even if you choose a different installation directory.
</Warning>

### Run two versions side by side

To keep an older version (for example, 2.7) installed alongside a newer version (for example, 3.0):

<Steps>
  <Step title="Rename the existing installation folder">
    Before installing the new version, navigate to the existing installation folder — by default `C:\Users\<UserName>\AppData\Local\Programs\ABBYY\Vantage\AdvancedDesigner` — and rename `AdvancedDesigner` to include the version (for example, `AdvancedDesigner_2_7`).
  </Step>

  <Step title="Install the new version">
    Run the new installer. Because the original folder was renamed, the installer creates a fresh `AdvancedDesigner` folder rather than overwriting the older install.
  </Step>

  <Step title="Create a shortcut for the older version">
    Create a Windows shortcut pointing to the executable inside the renamed (older-version) folder so you can launch either version on demand.
  </Step>
</Steps>
