How do I activate a Resprite product key on Steam?

This guide is for users who received a Resprite product key for Steam, also called a CD key. If you bought Resprite directly from the Steam store, install it from the Library of the account that made the purchase; you do not need a separate key.

Check your Steam account before activating. A key can be used only once and is tied to the account that activates it. On another computer, sign in to that same account to install Resprite; do not enter the key again.

Activate in the Steam client​

  1. Sign in to the Steam desktop client with the account you want to use for Resprite.
  2. Click + Add a Game in the lower-left corner, then Activate a Product on Steam…. You can also find this option in the Games menu at the top.
  3. Enter the complete key and follow the wizard. Once activation finishes, check that the product listed in the result is Resprite.
  4. Open your Library, search for Resprite, then install and launch it. If you cannot install it, check the system requirements.

The Add a Non-Steam Game option only adds a shortcut to your Library. It does not activate a key or grant a Steam license.

See Steam’s official guide: Activating a Product on Steam.

Activate in a browser​

You can also use Steam’s product key activation page. Sign in, confirm that you are using the intended account, then enter your key and follow the page instructions. After activation, open the Steam desktop client with the same account and install Resprite from your Library.

What if the key is not working?​

  • Invalid key: Confirm that it is a Resprite key intended for Steam. Copy the complete key without extra spaces, and check for missing or confused characters if you typed it. If it is still rejected, contact the seller or the organization that issued it.
  • Duplicate or already-used key: The key has already been activated on a Steam account and cannot be activated again. If you previously used it, sign in to or recover that account. If you have never successfully activated it, contact the seller or issuer.
  • Country or region restriction: Check the exact error and the regional terms supplied with your key, then contact the seller or issuer. Regional conditions can vary between keys; do not assume that every key has the same conditions.

Steam provides more detail about invalid and duplicate retail keys and region restrictions.

When asking for help, include the error text or a screenshot, where you obtained the key, when you tried to activate it, and your operating system. If you need help from Resprite, use our support channels. Do not post your full key in a public community.

Activation succeeded, but Resprite is missing from my Library​

  1. Confirm that Steam reported successful activation and that the product in the result was Resprite. If a different product was activated, contact the key issuer.
  2. Check that the client is signed in to the same account you used for activation, then search your Library for Resprite.
  3. If it is still missing, contact Steam Support with your activation confirmation.

If Resprite launches with trial limits or an account purchase prompt, check that you opened the edition installed from your Steam Library. The Steam edition does not require a separate in-app Premium activation code or the mobile stores’ Restore Purchase process. See how purchases work across stores and platforms.
