Bugs and Support

Windows Zwift launcher 1.1.13 white screen:
Clicking on the shortcut, for 3 seconds a white screen is popping up, after that the white screen is gone, zwift is totally closed, it is gone.
3 days ago, Zwift was working perfect!

I already did:

  • Uninstall Zwift, and did a reinstall. Did not work.
  • Did a new installation of my whole laptop yesterday at: ‎30-‎1-‎2025
  • Install Zwift on my new installation, but was not working, got the same problem.
  • Delete Zwift + program files and reinstall it; Used reno installer pro to delete Zwift compleet from my laptop.
  • Delete all browser cookies, history and stuff from Edge, Google Chrome, Internet explorer again.id
  • Removed the latest windows updates that I installed in the last days.
  • Reinstalled these updates afterwards, it had no effect on the crash.
  • Command prompt window, type SFC /scannow
  • So the system file checker utility checks the integrity of Windows system files and repairs them if required. Was nothing to repair. Rebooted the computer.
  • In commandprompt: Cleanup-Image /RestoreHealth. Was nothing to repair.

Seems to be that something is wrong with ‘prefs.xml file not found’.
By the way: Zwift is working on my mobile telephone IOS without a problem!
So the problem is only at my Windows laptop!
Please help!

Hi @AlCaponeCycling

If a crucial file like prefs.xml is not where the launcher expects it to be - you should delete everything related to Zwift by following the Re-installing Zwift support artilcle. This is a more through uninstall process than the Windows OS Uninstall utility.

8 GB of RAM is Zwift’s minimum spec.. While Zwift might install, your computer is going to struggle running any 3D game. Is the motherboard one that allows you to install more RAM yourself?

I fixed it, by running the file Webview2Setup which you can find in the Windows Zwift map. Webview file is related to Microsoft Edge.

Hi, can you clarify how you did this? Thanks

Step 1) Go the Zwift website to download the Zwift setup for your Windows pc. You can find the download button af the bottom of the page.

Step 2) Run the ZwiftSetup.
Step 3) Go to your Zwift install map, for example: C:\Program Files (x86)\Zwift
Step 4) You will see in the Zwift map a lot of files. Double click on the file: Webview2Setup to run it.

After running this file, the white screen problem should be fix.
