I can no longer start the game .
Ticket raised
Iâve got the same problem. Tried on 2 laptops same result on both.
Have you tried uninstalling and reinstalling? The upgrade may have had an error during the process.
Yes! And moved the Zwift folder! 
And me. Logged out and in, restarted pc many times and uninstalled and reinstalled Zwift. Email sent to support.
Iâm having the same issue. After updating I Zwift wonât open; tried uninstalling and reinstalling several times without any success.
Support ticket raised.

And all of your computers/PCs meet our minimum required specs? Because Zwift worked with computers below spec but constant improvements and updates to our maps could cause them to not work at any update.
EDIT: I did a quick look and, unfortunately, every person here has a graphics chip that is below minimum spec. They are either Intel HD Graphics 3000 (or old enough that it doesnât even have a number at HD Graphics). Our minimum has always been an Intel HD Graphics 4000 or newer - this was set during our Beta period as well. That it has worked until now is fortunate but you will need to upgrade your graphics (if a desktop) or use something akin to AppleTV or similar.
As the game continues to improve, with more and more objects and road to ride, it will run into these limits from update-to-update, unfortunately.
Android is in Beta and is working fairly well, so thatâs one option. AppleTV (as mentioned previously) is fairly inexpensive option (the AppleTV 4k runs it particularly well). Or, perhaps, itâs time to upgrade your rig!

UPDATE: It might be an actual driver issue with a very specific driver for these chipsets. We still highly recommend you upgrade, but weâll be doing some testing to see if we can identify what the issue is and issue a fix.

thanks, after the update from today, Zwift is running fine (Intel HD Graphics 3000)!
But as you mentioned, upgraded my system with a dedicated graphics card too.

update 9/10
new update downloaded looks to not include the patch for above sw issues
so problem once again present
game version 1.0.30588 reporting GLFW ERROR 65542: WGL: The driver does not appear to support OpenGL
please see if its possible to include the patch into the delivery stream
I have exactly the same problem, [17:36:56] GLFW ERROR 65542: WGL: The driver does not appear to support OpenGL
this after more than a year of no issuesâŚhow can this be fixed without me buying a new computer?
InvestigatingâŚ
@darren_charles Can you all try opening Zwift in windowed mode? In your prefs file (Documents/Zwift folder) delete the line <âFULLSCREEN>1</FULLSCREENâ> then run Zwift and see if you get past that error.
@Vincent where in the prefs file? assume itâs one of the options under ?
Ahh markdown messed up the formatting. Here: <âFULLSCREEN>1</FULLSCREENâ>
No joy deleting this line unfortunately, same issue.
FWIW my setting was actually 0 so after deleting the line and retrying, I also changed it to 1 and then got the message âZwift requires OpenGL3.1 or higher to run. Donât worry though your computer probably supports it, you may just need to update your graphics drivers. If you need help with this, please contact Zwift supportâ
Same as PeterDG
This is a little frustrating. Iâve been running Zwift on 2xxx series I7 with HD3000 since the beta.
It worked until two updates ago. Then the cant find OpenGL3.1 blah blah so update drivers. Drivers are fully updated.
Zwift update a few days ago fixed this problem and I was back in Zwift with no issues. Itâs not as smooth as my 1080TI, but the HD3000 really is fine for Zwift. Rode yesterday with no issues.
New update today has broken it again. The edit to the prefs file gets rid of the open GL error message, but Zwift still will not load.

I have the same issue. Till last Sunday I never had an issue with Zwift and all of a sudden, after Zwift launched some updates, the Zwift app wouldnât start anymore. I already sent a ticket to support and they told me to delete 1. The problem is that that line isnât in the prefs.xml so I couldnât delete it.
I also already removed and reinstalled Zwift but without any result.
When I look at the log files I always see appear : âGLFW ERROR 65542: WGL: The driver does not appear to support OpenGLâ.
It looks like a driver problem but Intel tells me that I have the latest driver version on my computer (Windows 10).
Will this issue be fixed by Zwift soon?
