Desktop Agent External Authentication: Failed to launch browser process.

adamharkus — Thu, 27 Feb 2025 09:52:18 GMT

I have setup Desktop Agent (v3) and registered and external authentication (for Office365) fine.

However, I can't reliably set this up for others. For one colleage it works, but for two others they get the following message when registering the external authentication.

An error occured during the external authentication registration. Failed to launch the browser process.

TROUBLESHOOTING: https://pptr.dev/troubleshooting.

All users defaulted to the Edge browser.

Any suggestions?

Hey there, did you manage to resolve this? I used to be able to and recently try to register it again and facing this same issue.

Hello. Not conclusive, but to resolve we rebooted, cleared cache in browser and changed default browser to edge, as it was Chrome. setup a new o365 connection and it worked. I think possibly the issue was default browser settings as chrome was the issue

Good luck!

Clearing my browser cache worked for me!
