Update failed code z117


I am a Windows 11 user and trying to use zwift, but since last week, I have been trying to update app and there is always the error Z117 at line 602 in patcher.cpp. What can I do?

If you can use the app as it is and everything is fine, do not insist about getting the update. I installed the update and I regret it.
Just saying.

That is the issue… I can’t use the app anymore… :frowning: trying all the things that I have seen in forums, but no solution to my problem

If I were you, I would uninstall the app and install again, instead of trying to update.


This issue is in a a few threads already but the post below seems to quote a workaround provided by Zwift to a user - hope it works for you. You can also search in the thread for Z117 for other’s comments/experiences (and also search the forums for same - seems to be lots of posts on this!).

One workaround is to tether to your phone’s mobile connection and upgrade that way.
