However, no one seems to be able to figure out how to fix the Unable to Initialize Steam API problem. However, some people have attempted to resolve this error, and we’ve compiled a list of some of them to assist you in resolving the Unable to Initialize Steam API error.



Solution 1: Reinstall Steam to fix the Unable to Initialize Steam API Error

Reinstalling Steam will help you address this issue, but first we must uninstall it, which will delete your game data, which will need to be re-downloaded afterwards. The following are the steps:

Step 1. Open Steam by double-clicking it or searching for it in the Start menu and selecting the option at the top. When it opens, go to the top right corner and click the Steam button, then Settings from the dropdown menu. Look for the Downloads tab, then select Steam Library files from the drop-down menu.

Step 2. You’ll see a list of the libraries you use, as well as the folders you should remember to back up. C:Program Files(x86)steam is the default folder to look in. In the right pane, open any folder and select This PC or My Computer. Locate the SteamApps folder in the above location.

Step 3. Paste the folder somewhere other than the Steam folder. It’s great if you save it to your desktop. Repeat with the remaining folders. After you’ve uninstalled Steam, re-add all of the folders to the Steam Library as you did before.

Continue removing steam from your PC when you’ve finished backing up the game installation. The steps are as follows:

Step 1. First, log in using an administrator account because only the administrator has the ability to uninstall apps.

Step 2. Double-check that you followed the procedures above for each folder on your computer, and take note of their proper locations so you can add them back after reinstalling Steam.

Step 3. In Windows 10, click the gear icon to enter the settings menu. Otherwise, go to the Start menu and select Control Panel. From the top right corner, select View as Category, and then click Uninstall an application from the Programs section.

Step 4. When you click on Apps in the Setting app, a list will appear. Locate and click on the Steam entry. Uninstall it by selecting the button above the list and accepting the dialogue boxes that popup. To uninstall Steam, follow the on-screen instructions and then restart your computer.

Solution 2: Restart Steam After Opting Out of the Steam Beta

Step 1. Open your Steam PC client on your Desktop by double-clicking it or searching for it in the Start menu and selecting the first choice that appears.

Step 2. Select Settings from the Steam option at the top of the client’s screen menu. While still in the account tab of the Settings, click the change button under the Beta participation area.

Step 3. Double-check the Beta participation box, then press to reveal the drop-down menu. Opt-out of all beta programmes by selecting the “Note: Opt-out of all beta programmes” option. And then save the adjustments you’ve made.

Step 4. Shut down Steam altogether. To do so, go to the Steam Window and pick Steam from the top left menu. Exit should be selected. (Do not escape by pressing the x button in the top right corner.)

Step 5. Use Task Manager to terminate all Steam-related tasks. To open the Task Manager, press Ctrl + Shift + Esc at the same time. Press Ctrl + Alt + Del at the same time to bring up a pop-up blue screen; select Task Manager from there. Otherwise, look for it in the Start menu.

Step 6. Click on more details in the lower left corner of the window to enlarge the Task Manager. Any Steam-related processes, such as Steam.exe, Steam Client Bootstrapper, or GameOverlayUI.exe, should be looked for. They’ll be discovered in background processes. By choosing them one by one, click the End Task option in the lower right corner.

Step 7. A notification will display informing you of the potential consequences of terminating certain processes on your computer. Simply select yes and confirm. Finally, repeat the previous step’s instructions and launch the game to reopen the client.

If the previous method does not work for you, try starting Steam.exe as an administrator:

Step 1. Right-click on the Steam.exe file in Windows and pick Properties from the context menu.

Step 2. Select the Compatibility tab in Windows’ settings and click the box next to it to execute it as an Administrator.

Step 3. Click OK, but make sure you accept all of the pop-ups that display when the admin capabilities are activated.

Solution 3: Disable Comodo’s Auto-Containment

If you use Comodo Antivirus, you’ve probably run into some issues because the program’s automatically active feature, Auto-Containment, sometimes prevents legitimate programmes. As a result, you need either disable it or remove the game’s executable from the list of restricted programmes.

Step 1. To open Comodo Internet Security, double-click it on the desktop or in the System Tray.

Step 2. From the home screen, select the Settings menu and then the Containment tab. By clicking on the sub-section, you can access it.

Step 3. After that, a checkbox will appear at the top of the Windows prompting you to enable it. Simply uncheck it to turn off the feature that prevents some programmes from executing.

Step 4. A list will display below; navigate to the executable for the game and switch off the slider to stop the programmes from being blocked. Save your progress and resume the game.

Solution 4: Create a Firewall Exception for the Game’s Executable

Step 1. Open Control Panel first, then search for this tool using the Start button, the magnifying glass, or the circular Cortona button on the left side of your Taskbar. Navigate to the bottom of the Control Panel to find the Windows Firewall Option, then adjust the view to large or small icons.

Step 2. Select Allow an app or feature from the left-hand list of options after clicking on the Windows Defender Firewall. A drop-down menu will appear. Go to the entry for the issue game and check the boxes next to both the public and private networks.

Finally, click OK. Restart your computer, then use Steam to reinstall the issue game. Check to see if the error notice “Unable to initialise Steam API” still appears.
