# Error Code: z112

You see error code z112 when Zwift can't download or verify an updated file on your PC.

## Possible Causes

*   Unstable or slow internet connection.
    
*   Not enough available disk space.
    
*   VPN or proxy interrupting downloads.
    
*   Backup or sync software accessing the same files (for example, OneDrive or Dropbox).
    
*   Zwift folder stored on a network location instead of your local PC.
    

## Resolution

Follow these steps in order. Check if the issue is resolved after each step.

1.  Check your internet connection.
    
    *   Restart your router.
        
    *   Run a [speed test](http://www.speedtest.net/) to confirm your connection is stable. Select a server in Los Angeles to ensure accurate results.
        
2.  Free up disk space.
    
    *   Make sure you have at least 5 GB of free space on your drive.
        
3.  Disable VPN or proxy.
    
    *   Temporarily turn off any active VPN or proxy service.
        
4.  Pause backup or sync apps.
    
    *   Pause apps like OneDrive or Dropbox while Zwift updates.
        
5.  Verify Zwift folder location:
    
    *   Make sure Zwift is installed on your local PC, not a network folder.
        
    *   If your Zwift folder is located on a network folder, uninstall and reinstall Zwift.
        

### Verify Folder Location

1.  Locate the **Z** icon in the taskbar notification area.
    
    *   If needed, select **˄** to show hidden icons.
        
2.  Right-click the **Z** icon and select **Open Logs Folder**.
    
3.  Check the file path.
    
    *   Confirm the folder is under **This PC** and not a network location.
