What steps are involved in uploading and publishing my game?

Following that, you can zip your game and upload it through the Web UI upload form, use our Command-line Tools for direct upload from your PC, or use our Unity extension. After upload, your file contents will be processed, and you’ll see a progress bar. Once the upload is complete and successful, click the red Publish button on your draft version view to publish your game. A notification will be sent when your version is published and ready for download.

Where can players download my game?

The game can be accessed by players through the launcher application. This application can be downloaded from your application’s page, or you can share a direct download link with your players.

How does PatchKit handle updates?

PatchKit operates on binary diffs, making updates seamless. For every published version, a binary diff is generated on our servers and automatically downloaded and applied by your players when they launch the game. This process typically takes only a few seconds based on network and PC performance.

Can I use PatchKit for non-game applications?

Yes, PatchKit is not exclusive to games. Our Launcher component is game-oriented by default but can be used to distribute any software.

Can I use PatchKit behind a firewall?

Yes, but you’ll need to whitelist all *.patchkit.net domains (using a wildcard) and ensure specific ports are open. For optimal performance, we highly recommend opening the following ports:

  • Outgoing TCP 80
  • Outgoing TCP 443
  • Outgoing TCP 9292 to any *.patchkit.net
  • Outgoing UDP 443 to any IP

How can I avoid the “Windows protected your PC” popup when running the launcher?

This message is generated by Microsoft Windows SmartScreen to prevent unknown applications from running. You can either sign your code with a code signing certificate or wait for a while until SmartScreen recognizes that the application is not harmful. You can also instruct users to click on the More Info link and then the Run anyway button to bypass this popup.

What’s the difference between the runner and launcher in PatchKit?

In PatchKit, the Runner is a small application responsible for downloading the newest version of the Launcher. The Launcher is a larger application used for downloading the latest version of your software.

Why do we need a runner?

The Runner allows us to release any potential updates for the Launcher. It doesn’t use any patching algorithms to update the launcher - it simply redownloads the whole launcher to keep the process simple and efficient.

What are the common use cases for PatchKit?

PatchKit is versatile and caters to a variety of use cases. These include game marketplaces, closed/open early access, self-publishing as the primary or an additional distribution channel, educational games, simulators, and training software.
