# Error Code: z117

You see error code z117 when Zwift can't write files to your PC.

## Possible Causes

*   You’re not using an administrator account.
    
*   Your administrator account username contains special characters (symbols or punctuation).
    
*   Another program is interfering with Zwift (for example, antivirus or backup software).
    
*   Not enough available disk space.
    
*   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.  Run Zwift as administrator.
    
    *   Right-click the Zwift file and select **Run as administrator**.
        
2.  Check your account username.
    
    *   Remove special characters from your administrator account username.
        
    *   Create a new administrator account without special characters.
        
3.  Check antivirus or security software.
    
    *   Make sure your antivirus software isn’t preventing Zwift from writing to your account folder.
        
    *   Allow Zwift through Controlled Folder Access if enabled (see [Microsoft documentation](https://support.microsoft.com/en-us/windows/allow-an-app-to-access-controlled-folders-b5b6627a-b008-2ca2-7931-7e51e912b034)).
        
    *   Add Zwift as an exclusion in Windows Security(see [Microsoft documentation](https://support.microsoft.com/en-us/windows/allow-an-app-to-access-controlled-folders-b5b6627a-b008-2ca2-7931-7e51e912b034)).
        
4.  Pause backup or sync apps.
    
    *   Pause apps like OneDrive or Dropbox while Zwift updates.
        
5.  Free up disk space.
    
    *   Make sure you have at least 5 GB of free space on your drive.
        
6.  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.
        
        Re-installing Zwift will delete any custom workouts stored locally on your computer. We recommend backing up any custom workouts before you begin.
        

### 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.
