Update Failed during patching Error Code Z117

Hi,I am new to Zwift and while Updating for the very first time I always get this message: Update failed during patching, Error Code Z117 at Line 602 in Patcher.cpp. What can I do?


From Error Code: z117

Issue Summary

This error indicates Zwift is having difficulty writing in the Documents folder on your computer. Here’s some of the reasons this may happen:

  • You are not an Admin on your machine.
  • Another program on your computer is interfering with Zwift.
  • You have less than 4GB of free space on your hard drive.


These are a couple possible workarounds:

  • Right-click on the ZwiftInstaller file and choose ‘Run as Admin…’ even if you already have Admin access on your computer.
  • If you have an antivirus program installed, make sure it’s not preventing Zwift from writing to your account folder.
  • If you have a sync program (e.g. Dropbox, Microsoft OneDrive) installed, make sure it’s not syncing your Documents folder.
  • Make sure your default Documents folder is accessible.

If the Documents folder is saved to a disconnected network drive, it may not be accessible.

  • If the workarounds above don’t work, try deleting the Zwift folder under Documents, and then re-launching Zwift.
