Install and Update Stream to 3D

Use the section for the store where you own Stream to 3D. Steam manages the application through the Steam client. Gumroad and Itch.io provide a Windows installer that can be run over an existing installation when updating.

Steam

1. Open the Steam client and select Stream to 3D in your Library.
2. Select Install, choose the Steam library location and allow Steam to complete the download.
3. Start Stream to 3D from the Steam Library. A desktop shortcut is optional and depends on the choices made in Steam.

Steam validates the purchase and any feature entitlements through the signed-in Steam account. A separate licence key is not entered into the Steam installer.

Steam library folders can be placed on different drives. To find the installed files, right-click Stream to 3D in the Steam Library and use Manage > Browse local files. A typical location is:

C:\Program Files (x86)\Steam\steamapps\common\Stream to 3D

Steam updates

When Stream to 3D reports that an update is required, close the application and allow the Steam client to download and install it. Launch Stream to 3D again only after Steam has completed the update.

If a required or optional supporting application is missing after installation or an update, use the Steam optional-tools repair guidance. Reinstalling the main Steam application does not necessarily rerun every separately installed optional tool.

Gumroad

1. Open the download page or Gumroad Library entry for the Stream to 3D edition you purchased.
2. Download the current Windows setup archive from that official purchase page or use the Download action in a Stream to 3D update prompt.
3. Open the archive and run the Stream to 3D setup application.
4. Enter the Gumroad licence key supplied with the purchase when the installer asks for it.
5. Review the installation location and component choices, accept the applicable terms if you agree, and complete setup.

The current setup archive uses the published archive password streamto3d. This is an archive password used when opening the downloaded setup package. It is not your Stream to 3D licence key and does not grant access to the product.

The default application location is:

C:\Program Files\StreamTo3D\StreamTo3D.exe

The Gumroad installer does not automatically create a desktop shortcut. You can create a Windows shortcut to StreamTo3D.exe after installation if useful.

Gumroad updates

Supported earlier versions check for required updates when Stream to 3D starts. Select Download in the update prompt, close Stream to 3D, and run the downloaded installer over the existing installation. Keep the existing destination folder unless you deliberately want to move the application.

Itch.io

1. Open the Stream to 3D download page associated with your Itch.io purchase.
2. Download the current Windows setup archive or use the Download action in a Stream to 3D update prompt.
3. Open the archive and run the Stream to 3D setup application.
4. When asked, enter the Itch.io Download Key or paste the complete Itch.io Download URL. This is the URL containing /download/ that Itch.io provides for the purchase.
5. Review the installation location and component choices, accept the applicable terms if you agree, and complete setup.

The current setup archive uses the published archive password streamto3d. The archive password is separate from the Itch.io Download Key or Download URL used to validate the purchase.

The default application location is:

C:\Program Files\StreamTo3D\StreamTo3D.exe

The Itch.io installer does not automatically create a desktop shortcut. You can create a Windows shortcut to StreamTo3D.exe after installation if useful.

Itch.io updates

Supported earlier versions check for required updates when Stream to 3D starts. Select Download in the update prompt, close Stream to 3D, and run the downloaded installer over the existing installation. Your Download Key remains associated with the purchase.

Installer components

The Gumroad and Itch.io installers can download and launch separately licensed supporting applications used for media compatibility, playback, conversion or Live Sources. The installer describes which choices are recommended for the selected edition and which are optional.

• Use the normal or compact selection for the usual first installation.
• Leave a component unselected only when you know that a suitable installation is already available.
• Some component installers open separately and may show their own licence or Windows prompt.
• After setup, open Tools in Stream to 3D to confirm that the supporting applications you intend to use are detected.

See Tools and Dependencies for the customer-facing checks and repair routes. Reinstall or repair only the component associated with the problem instead of repeatedly removing the whole product.

Windows installation prompts

Windows may display User Account Control, Microsoft Defender SmartScreen or another security-product prompt for a downloaded installer or one of its separately launched component installers.

• Continue only when the file came from your official Steam, Gumroad or Itch.io purchase route, or from a download link supplied by IWAHDK LTD.
• Check that the product and publisher details shown are consistent with the file you intended to run.
• Do not disable Windows security globally to complete installation.
• If Windows blocks the installer or uninstaller without presenting an appropriate route to continue, check Windows Security > Protection history and use the Support page before deleting application or tool files manually.

Stream to 3D requires administrator approval because the installer writes to Program Files and installs or configures system-wide supporting applications. A normal prompt does not mean that you should approve an unexpected or unofficial download.

First launch

The Gumroad and Itch.io installers open the Welcome to Stream to 3D page after setup. They do not automatically start the Stream to 3D application. Steam users can open the same Welcome guidance before launching from the Steam Library.

1. Start Stream to 3D from its store or installation location.
2. Allow the initial purchase and feature check to complete while connected to the internet.
3. Open Tools and confirm that the supporting applications needed for your intended workflow are detected.
4. For the first functional test, use Play with a short, familiar 2D video file before introducing a Live Source.

For an activation error or feature reported as locked, use Licensing and Activation. For a missing supporting application, use Tools and Dependencies. For other first-use problems, start with User FAQ and Troubleshooting.
