Fix for Error Message 0x3000064 after Remote Desktop mote update to 10.5.0 on Mac

Question

After installing the most recent 10.5.0 update, I am now receiving an error code 0x3000064 and am unable to gain access to my remote desktop with my organization. Does anyone have a fix for this or now how I can get the previous version back?

Answer 1

Hi,

We received several users' posts to report the same error you have encountered. This might be an issue of the latest version of remote desktop app for mac, but there is no related official document at the moment since the update was just released several days ago.

If you would like to get back to the previous version, please try to uninstall the current app and then check if you can download and install previous versions from below link.

Also, we suggest that you could post this error to the uservoice and let others vote for it to see if there will be any feedback from the product team.

Hello,

We are facing the same issue since 10.5.0 arrived. We have about 20 users impacted using MAc client. PC clients are not impacted. After several tests we have determined that the fault is related to RPC over HTTPS implementation that seems to be broken.

The only workaround I have found is to use DNAT on our firewall instead of the reverse proxy to be fully transparent between the client and the RDS GW.

Last year we faced the same issue with v10.3.4 and was fixed with version 10.3.5

Hello,

By using apple store applications like MS Remote Desktop Client, downgrade is impossible.

As this feature was working fine before release 10.5.0, I cannot understand why we should wait for other people to vote to have a feedback from dev team.

Hi,

Thanks for all of you to post this issue. We have also submitted this issue to our Product Team, so that they can investigate the issue as soon as possible. However, we cannot guarantee the fix date since it it out of forum's control. Appreciate your understanding.

If Beta version cannot work for you, please also try below to see if it helps.

Go to Microsoft Remote Desktop > preferences > General Tab> uncheck “use system proxy configurations “ and
Also uncheck “Use hardware acceleration ”

Thanks,

We have the same issue.
Downgraded manually to version 10.4.0. (could not find newer stable version)
Turned of auto update manually on 120 + mac computer.
Please roll out a fix asap.
And, if you check uservoice there are more and more users reporting the same issue.
