  • Select the Apply button.
  • Select the OK option.

4. Turn Off the Windows Firewall

5. Turn Off Third-Party Antivirus Software

The “An error occurred while updating Counter-Strike” error can also be due to third-party antivirus software, which include firewalls. Steam users have fixed the issue by uninstalling antivirus utilities.

At the very least, some players might need to disable their antivirus software by right-clicking the utilities’ system tray icons and selecting a disable or turn off setting.

If that isn’t enough, try clean booting Windows. That will remove third-party antivirus utilities, and other software, from the startup. Follow the guidelines below to clean boot Windows.

  • Open Run with the Windows key + R hotkey.
  • Then open the System Configuration window by entering ‘msconfig’ in Run and clicking OK.

  • Select the Selective startup radio button.
  • Uncheck the Load startup items check box.
  • Select the Load system services and Use original boot configuration check boxes.
  • Click the Services tab shown directly below.

  • Select the Hide all Microsoft services option first.
  • Then click the Disable all button to uncheck all the third-party services check boxes.
  • Select the Apply option to confirm the new settings.
  • Then click OK to close the window.
  • Press the Restart button on the dialog box window that opens.

  • Open Steam and launch Counter-Strike again. If the game updates and starts, then you probably need to get rid of the antivirus software.

6. Delete the Appcache Folder

Deleting Steam’s appcache folder is another confirmed resolution for the “An error occurred while updating Counter-Strike” error. To do that, close the Steam client software if it’s open. Open File Explorer. Open the Steam folder, which will probably have this File Explorer path: C:Program FilesSteam or C:Program Files(x86)Steam. Then select the appcache subfolder, and press the Delete button to erase it.

Those are a few of the resolutions that have fixed the “An error occurred while updating Counter-Strike” for some Steam users. For further resolutions, users can set up a Steam Support account to send a support ticket.
