Hi, this week started Zwift again and got the update
Since I start up , it gives the login screen and says Welcome.
Then it turns to the full blue screen and there it stays all the time.
I have Windows 7 desktop
With 4GB ram memory
2GB MSI video card
Also on my laptop it will not start , while we tried on a computer at work and that worked well.
i have the same problem…again!
Here too, after update no longer starts the zwift, support helps me
I use windows 10
I still can’t start it on my pc. I uninstalled, updated, and installed again. This was after the update on Friday. I ended up using my Mac laptop. So far no problems there!
I have the same issue
both of my computers were working just fine before the update and now I cant use it.
sucks cause I’m getting ready for a competition and I need it to work helppppp
Same issue, since update screen freezes. Can NOT get on. Please let us know what needs to be done?
I cant log in on my laptop. my mac desktop is working fine though.
really annoying but I would hope as we are paying for this service Zwift will be working on fixing whatever they have done ASAP
Support gave me the heads up my problem was to do with the sound card. I actually had nothing plugged in on the PC I use and plugging a jack to jack cable in to the green socket (audio out normally) and fooling the PC into think it had headphones connected allowed Zwift to launch. Result.
Just had a small update , and everything seems to work fine now.
At least on my Desktop with Windows 7, which I run Zwift on normally.
Thanks Zwift.
hoped this mornings update was going to sort it out but no joy. even tried the jack plug trick.
still no joy.
On my laptop (Windows 10) it is not solved yet, but normally don’t use that for Zwift.
I have the same problem with a macbook air
The latest update seemed to resolve the issue with my pc. Thank you!
After signing in the screen states, “Log in Successful” but then the screen freezes and states “ZwiftApp quit Unexpectedly”. Any suggestions?
Had no issues with Windows 10–used my Surface when Zwift wouldn’t start on the Mac connected to the TV. But the screen on the Surface is so small. 
On Mac OS X 10.7.5 “ZwiftApp quit unexpectedly” after entering password. I tried uninstalling and re-installing but I don’t think all of the files are cleaned up on a Mac when uninstalling because after RE-installing I got the message, “Welcome back Jeremy”. Tried uninstalling / restarting / downloading / reinstalling like 3 times.
Please advise.
