Microsoft Remote Desktop Mac client not working after upgrade to 10.8.0 error 0x3000064

John_Spencer I'm still getting error 0x3000066 on the latest beta release. Any idea when this might be fixed? 

Update to problem when running with McAfee Virus protection with firewall on:  I opened a ticket with McAfee and have a meeting with them Monday to see if we can resolve this issue. I will keep this discussion up to date.

I tried keeping 10.8.0, with running "

defaults write com.microsoft.rdc.macos ClientSettings.DisableOnPremWebSocketGateway true" in Terminal, but RDP client showed 0x104 error. My Mac running Ventura 13.1. Is there any problem with this?

If you're running McAfee virus protection, turning off the firewall will resolve this issue.  Not sure what to open up in the firewll, so turning off was the only option.

Version 10.8.1 (2043) still not working...

hello

I have the problem with the access Remote Desktop. What does it mean?????

John_Spencer The problem still exists for us, and I've forwarded traces as requested - including a trace for the 10.7.9 beta release referenced above, which still works correctly in my experience.

To help us triage can you please collect some traces. Set the core log level to "Information", then start logging and repro the issue. Please send the logs to mailto:rdios@microsoft.com please. Thanks

Same here getting getting Error code: 0x3000064 when executing a downloaded RDP file.

Beta Version 10.8.1 (2043) DIDN'T work for me but it does show a different error message.

Hi, I confirm that version 10.8.1 (2041) works for me. 
Thank you.
