To add and play a non-Steam game, use the Steam desktop client’s Games > Add a Non-Steam Game to My Library option, select the installed game or its application, and add the shortcut. You can then launch it from your Steam Library. This creates a launch entry—not an installation or a Steam license—and Steam does not provide updates for the linked game.
If the game is already installed outside Steam, the shortcut can be a convenient way to keep it alongside your Steam games. If you are using Steam Deck, the addition step happens in Desktop Mode. In either case, listing a game and getting it to run are separate questions: a successful shortcut does not guarantee compatibility.

It puts a shortcut to an application in your Steam Library so you can launch it from Steam. Steam Support puts the limitation plainly: “This will only add a shortcut to your game in the Steam client.” The game remains outside Steam’s licensing and update systems: the shortcut does not prove ownership to your Steam account, and Steam will not download updates for it. Steam’s support article explains what the shortcut does.
Think of the shortcut as a pointer to software you already have, rather than a copy of the game inside Steam. Steam adds an entry to the Library and attempts to start the application associated with that entry when you choose Play. It does not transfer the game’s files, install the game for you, or change which company or service manages its updates. You still need the game and its launch application to be available on the device.

That distinction matters if you bought a key from a retailer. If it is a key that activates the game on Steam, use Games > Activate a Product on Steam and follow the activation flow. If the game cannot be added with a Steam key and is already available on your device through another source, add it as a non-Steam shortcut instead. The Steam Support guidance for retail and non-Steam games distinguishes these routes. Adding a shortcut does not convert a third-party purchase into a Steam license.
The two routes solve different problems. Product activation is for a key that gives your Steam account a Steam game license. A non-Steam entry is for launching an application that remains outside that Steam licensing route. In the latter case, the shortcut is not proof of ownership in Steam, and Steam does not become the provider of the game’s updates. If you are unsure which route a key uses, follow the activation instructions for that key rather than expecting the shortcut option to redeem it.
How do I add a non-Steam game on a PC?
Have the game installed first, or know where its executable or application is located. Adding the entry does not download or install the game. Then use the Steam desktop client:
- Open Steam and sign in if needed.
- In the top menu, choose Games > Add a Non-Steam Game to My Library.
- In the list, select the installed game if it appears. If it does not, choose the browse option and navigate to the game’s executable or application.
- Choose Add Selected Programs.
- Open your Library, select the new non-Steam entry, and choose Play to launch it.
The menu adds a shortcut for the application you select; it does not move the game’s files into Steam. If you browse manually, select the application that launches the game rather than an unrelated file in its installation folder. If the game normally starts through another application or launcher, the entry may need to point to the application used to start it. The exact file and behavior vary by game, so the game’s own installation or support information may be needed to identify the right application.
If the game appears in Steam’s selectable list, you can choose it there. If it is not listed, the browse option lets you locate an application on the device. The important requirement is that the selected item be the application you want Steam to launch. Selecting a folder or an unrelated file will not install the game or identify the correct launch target for you. If you do not know which application starts the game, check the game’s own documentation or support information.
After adding it, return to the Library and try Play. If nothing happens or the wrong application opens, that does not necessarily mean the shortcut feature is unavailable; it may mean the selected target is not the one the game needs. Revisit the entry and verify the application you intended to add. For games that depend on a separate launcher, whether that launcher is the right target can vary by title, so avoid assuming that the main game executable and the launcher are interchangeable.

How do I add a non-Steam game on Steam Deck?
For an application already installed on the Deck, switch to Desktop Mode and add it through the desktop Steam client. Afterward, Steam says it appears in the Deck interface’s non-Steam library tab.
- From Gaming Mode, open the Steam menu, choose Power > Switch to Desktop.
- In Desktop Mode, open the Steam desktop client.
- Choose Add a Game > Add a Non-Steam Game.
- Select the installed application from the list, then add it.
- Return to Gaming Mode and look for the entry in the non-Steam tab of the Library.
These steps register the application; they do not establish that it will run correctly in Gaming Mode. Steam’s Steam Deck and Steam Machine Desktop FAQ covers adding desktop applications, while its Steam Deck software and troubleshooting guide addresses compatibility and troubleshooting.
The sequence matters: the desktop client is where you add the already-installed application, and the non-Steam tab is where Steam says to look for the entry after returning to the Deck interface. This process is for an application installed on the Deck; it is not a way to download an outside game through Steam. If you have not installed the application yet, the shortcut alone will not supply it.
It is useful to test the entry after switching back, but do not treat its presence in the Library as a compatibility result. Steam’s compatibility categories and troubleshooting steps address whether a game or application can run, not whether it was successfully added as a shortcut. If a Deck entry launches poorly or not at all, troubleshoot it as an application compatibility or stability issue rather than repeating the add step without checking the target.
Why might the shortcut appear but the game not launch?
Creating a shortcut and getting a game to run are separate steps. A shortcut only tells Steam what application to try to launch; the game may still depend on its operating system, compatibility setup, or other requirements.
On Steam Deck, Steam’s compatibility labels for Steam games are Verified, Playable, Unsupported, and Unknown. For an individual Steam game, Steam recommends checking the compatibility information on its store page. Those labels are not a guarantee for a non-Steam shortcut: a game added manually may need a different compatibility setup, and a successful shortcut registration is not a compatibility rating.

Use the labels as context rather than a promise about an application you have added yourself. In particular, the fact that a Steam game’s store page lists a compatibility category does not give a manually added non-Steam application that category. First establish that the shortcut points to the intended application; then consider the operating system and compatibility tools that may be needed to run it.
Steam’s client update notes dated October 13, 2026 say that Windows binaries registered as non-Steam games run in Proton by default on Linux, and document an option to choose a compatibility tool. This describes the behavior recorded in those notes, not a promise that every Windows game will run. If a game does not start, you can try a different compatibility tool for that entry:
- In the Steam Library, open the non-Steam game’s Properties.
- Open Compatibility.
- Enable Force the use of a specific Steam Play compatibility tool.
- Select an available tool and try launching the game again.
The setting is per entry: it is a way to choose a compatibility tool for that game rather than a guarantee that a particular tool will fix every launch problem. The October 13, 2026 notes describe Proton as the default for Windows binaries registered as non-Steam games on Linux, while also documenting the option to select a tool. Because this is version-sensitive client behavior, treat it as what the notes record—not a universal rule for every setup or a promise that all Windows games will work.
This is a troubleshooting option, not a universal fix. The game may still fail, behave incorrectly, or require a setup Steam does not provide. The October 13, 2026 Steam client notes also mention Steam Input controller configuration, but that does not establish that every game or controller setup will work.
What should I check if it still will not launch?
First confirm that you added the correct application and that the game itself is installed and starts as expected in its usual environment. Then treat the problem as a compatibility or application issue rather than assuming the shortcut failed: on Deck, review the game’s compatibility needs and, where appropriate, try the per-game compatibility setting above.
A practical order is to check the basic pieces before changing settings: is the game installed, is the application you added the one that starts it, and does that application start in its usual environment? If those checks are sound and the issue is on Steam Deck, consider whether the game needs a different compatibility tool. Changing the compatibility setting may be worth trying, but it does not resolve every issue and cannot supply a missing game or launcher.

If a non-Steam application is unstable on Steam Deck, Steam’s troubleshooting guidance recommends closing or disabling third-party apps installed through Desktop Mode and restarting the Deck. If the issue continues, contact the application’s product support. These steps address stability problems; they do not guarantee that an unsupported application will become compatible.
Keep the symptom in mind. A shortcut that does not open the intended program calls for checking the selected application. A program that starts but is unstable points toward an application or compatibility problem. Steam’s Deck guidance specifically recommends closing or disabling third-party apps installed through Desktop Mode and restarting when a non-Steam application is unstable; if instability continues, contact the application’s product support. Do not assume that the shortcut has made Steam responsible for fixing or updating the outside application.
Can I use Steam features with a non-Steam game?
Steam can launch the shortcut from the Library, and Steam’s client notes document Steam Input controller configuration. A controller is optional; the basic add-and-launch process does not require extra hardware. However, the fact that an entry is in Steam does not establish that every Steam feature, control scheme, or game function will work with it.
If you want to play with a gamepad, Steam Input configuration may be useful, but it is an optional control setup rather than a requirement for adding the game. The official client notes mention controller configuration; they do not recommend a particular controller model or establish universal controller or game compatibility. You can create and launch the Library shortcut without buying a controller or another accessory.

Choose based on what you have and what you want Steam to do. If you have a Steam product key, use the activation route so the game can be added to your Steam account as a Steam product. If the game is already available outside Steam and cannot be added by key, use the non-Steam shortcut to create a Library launch entry. The shortcut route does not turn an outside purchase into a Steam license.

| Question | Steam product activation | Non-Steam shortcut |
|---|---|---|
| When does it fit? | When the game has a key that activates on Steam. | When the game is available outside Steam and cannot be added by Steam key. |
| What does it add? | A Steam product to the account through the activation flow. | A shortcut to an application in the Library. |
| Does it install an outside game? | Follow the Steam activation flow for the key. | No. The game or application must already be available on the device. |
| Who provides updates? | Use the Steam product route for a Steam-licensed game. | Steam does not download updates for the linked outside game through the shortcut. |
The comparison is about the kind of entry, not two competing ways to install the same outside game. A shortcut is convenient for launching from one Library, but it does not change licensing or update responsibilities. When a key is intended for Steam, activate it rather than adding a shortcut as a substitute.
Does adding a non-Steam game cost anything?
The Steam shortcut procedure itself requires no purchase. It is a Library entry for a game you already have; it does not buy or install the game. If you want a controller, that is optional hardware for gamepad input, not a prerequisite for creating the shortcut. The sources for this workflow do not establish a required accessory or a particular controller recommendation.
Frequently Asked Questions
How can I add non-Steam games to my Library in Steam?
Open the Steam desktop client, choose Games > Add a Non-Steam Game to My Library, select the installed application or browse to it, and choose Add Selected Programs. Then open the Library entry and press Play. This creates a shortcut; it does not install the game or make it a Steam license.
Can I add a game to Steam before downloading it?
A shortcut does not download the game. The Steam workflow can point to an application on your device, but you will need the game installed and its launch application available before the shortcut can start it.
Will a non-Steam shortcut get Steam achievements or cloud saves?
Adding a shortcut by itself does not make the game a Steam license or establish that Steam provides the game’s services. Whether achievements, cloud saves, or other account features are available depends on the game and how it is distributed; the shortcut alone is not evidence that they are.
Can I add a game that uses a separate launcher?
You can add an application outside Steam if it is available on the device, but the selected shortcut has to launch the relevant application. If starting through the game’s own launcher is required, the correct target and whether it works on your system can vary by game.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsDoes a controller have to be connected to add a non-Steam game?
No. A controller is not a prerequisite for creating or launching the Library shortcut. Steam documents Steam Input configuration, but controller support and usable controls are not guaranteed for every non-Steam game.
The Bottom Line
Add a non-Steam game when you want a Library shortcut to software already available on your device. Use Steam product activation for a key that activates on Steam. On Steam Deck, add desktop-installed applications in Desktop Mode, then check the non-Steam tab; troubleshoot compatibility separately from shortcut creation. A shortcut is not an installation, Steam license, update service, or guarantee that the game or its controls will work.
