General questions

Why should I use Xsolla Launcher when I can create my own launcher?

Xsolla Launcher saves time and resources during the final stage of development or after the development of the game is completed. Xsolla Launcher is free for partners, excluding payment fees. Xsolla Launcher regularly releases new features for users and works with other Xsolla products, including in-game store, website builder, and login. Xsolla follows market trends.

How much is Xsolla Launcher going to cost me?

The price of Xsolla Launcher is already included in the Xsolla fee. Additional costs may apply when delivering games. However, using a P2P balancing system reduces shipping costs by an average of 80%.

How do I deliver game updates to Steam if I'm using Xsolla Launcher?

If you use the Steam launcher, you download the game build and launcher directly to Steam. In this case, Steam delivers and updates the game. If you want to deliver content using Xsolla Launcher and its CDN on Steam, please contact your project manager or email csm@xsolla.com.

Do I need to maintain two separate builds for Steam and a stand-alone? Or is it the same build that gets uploaded to Steam?

The number of builds depends on the method of integration with Steam. However, one assembly is often enough. The launcher allows you to collect user data into a single database if you support game delivery via multiple platforms. The launcher also supports end-to-end registration: if a user launches the game through Steam for the first time, they do not have to enter their data.

In this case, the user can visit your site outside the Steam system. They can authenticate using their Steam OpenID and become a member of your official community. After this, the user can write on forums, read news, find new games, etc.

I’m using Steam’s tools, including their launcher, and I have no CDN costs. What will change if I start using Xsolla Launcher?

Adding Xsolla Launcher to Steam with the game does not change the distribution logic; Steam is still responsible for distributing and updating games. The launcher CDN is not used in this case.

If you want to distribute the game yourself and use the launcher regardless of platform, Xsolla Launcher distributes game builds and updates using its CDN (G-core by default) or any other you request. Payment for traffic is not included in the standard payment commission and is paid separately on a monthly basis.

Xsolla has a special enterprise price for G-core that applies to all its customers.

Do you have a list of CDNs that are pre-integrated with your Xsolla Launcher? Do I need to contact the companies that provide CDNs for further integration? Can I use a CDN that is not on your list?

If you want to use another CDN provider, please contact your Customer Success Manager or email csm@xsolla.com.

Which games are displayed in the game list in Xsolla Launcher? All added games or only the ones purchased by a user?

The list contains all the games that have been added to Xsolla Launcher. The games purchased by a user have the Play button and the rest of the games have the Buy button or different buttons depending on game distribution type.

Can particular users get free game keys? How can they use them?

Yes, you can download game keys from Publisher Account and send them to your users for free in any way you wish. The users will be able to activate their keys in Xsolla Launcher.

Can users be authenticated in games automatically after they authenticate in Xsolla Launcher?

Yes, this is possible. To transfer user data from Xsolla Launcher to the game, use the –xsolla-login-token parameter. To get user data, you need to decode the parameter value.

What can I do if the Xsolla Launcher icon in the tray hasn’t changed after I changed it and rebuilt Xsolla Launcher?

Reinstall Xsolla Launcher.

Where can I find launcher logs?

To find the launcher logs:

  1. Open your launcher.
  2. Go to the launcher settings.
  3. Click Browse logs in the General section.

How does the game integrate with Xsolla Launcher?

To integrate the game with Launcher, create a project in your Publisher Account and download the game assembly. After that, you can add images for your game and configure additional settings in the interface.

Is there some kind of IPC solution in the SDK?

There is currently no IPC, as Xsolla Launcher doesn’t have features that require IPC communication. But we do plan to add features such as live streaming and a game store in the overlay that will require IPC (via SDK), at which time we’ll add it.

Is Xsolla Launcher supported on mobile or Mac?

Xsolla Launcher supports Windows and MacOS OS.

How is content populated on a game’s page in Xsolla Launcher?

You can fill out information for the content in the settings of each game in the Game Info section. You can also fill out content for the game page in the Game Titles section of Xsolla Launcher. To find out more, read the instructions.

Build Loader

When I upload a game patch via Build Loader, I receive the following error: "Attention! File path longer than 260 characters." How do I fix this?

In Windows, there is a limitation on the maximum length of the full path, so we recommend moving the game directory higher up in the directory tree, for example, C:/Patch. After that, pass the updated path to the game build using the command –game-path <path-to-game>. To learn more, please read the instructions.

I can’t start Build Loader. How do I fix this?

Build Loader is a command-line utility. Open the command-line interpreter, such as cmd.exe, in the directory with the build_loader.exe file and run the file using the following command: ./build_loader.exe To learn more, please read the instructions.

Publisher Account

When I log in to Publisher Account, it shows that I’m still using an old version of Launcher and need to create a new launcher. But, when I click the Try New Launcher button, our launchers show up. How do I fix this?

At the moment, Publisher Account allows working with the v2.x.x and v3.x.x versions of Launcher, but creating a v2.x.x launcher is no longer available. When you switch to the new version of the launcher, the settings are saved on your device. However, if you log in from a new device, the settings applied will be for the user of the old version of Launcher.

Games launching

Does the game require Xsolla Launcher to be running to work?

At the moment each game can have only one launcher build. You can use another game build for the draft version of launcher, but it can not be shared with end users.

The antivirus shows a warning window or blocks downloading when a user downloads a game. How do i fix this?

This is a false positive reaction of the antivirus to the download via P2P (peer-to-peer). The launcher uses P2P connections for downloading game files, so it connects to users through a shared public IP address that is used by multiple users or websites.
If you are using Malwarebytes software, please refer to their official comment regarding this matter.
To fix the error, the user should go to the launcher settings and disable the Use P2P (peer-to-peer) network option.
