 After today’s update (game version 1.0.12193), ZWIFT kept crashing after clicking on log in button. It seems to have problem with XAudio_2.7.dll but I haven’t upgraded my windows since last time ZWIFT ran fine on my system.

I already created a ticket but haven’t received any responses yet.

 

Anyone else seeing similar problems?

It looks like somehow ZWIFT update put a copy of bad XAudio2_7.dll into my System32 folder. After manually copied a good copy of XAudio2_7.dll to the system32 folder from another computer, this problem went away.
