[Solved] Spacedesk dose not work on Win 10 64bit?  

How to attach a zip file?

The diagnostic file please refer to the attachment.

Hi @sunnyboy0030,
Thanks for sending the diagnostic logs.

Could you also try to click the spacedesk tray icon in the notification area to open the spacedesk SERVER window, then click the menu "..." button and click the "Clear All Display Settings", then try again to connect.

By the way, what is the connection time below the error code on your viewer app?

Thanks for your rapid reply. I've tried to clear all the settings, but the problem was still there. The time shown below the error info is 10~14s.

Hi @sunnyboy0030,
Do you maybe have Nvidia ShadowPlay / screen recording / Instant replay currently running on your primary machine?
If yes, please disable it before connecting a spacedesk viewer.

I've disable the In-Game Overlay in Geforce Experience already, so this is not a case.

Hi @sunnyboy0030,
We are currently analyzing the log files, do you have VNC Mirror driver currently running on your machine?
If yes, can you try to switch it OFF then try to connect the spacedesk viewer.

Hi @sunnyboy0030,

Follow-up questions:
Did you recently update from Windows 7 to Windows 10 operating system?
If yes, was spacedesk already present before on your Windows 7?

Could you please also try the following and let us know the result:
- run command prompt as administrator
- type the command =>  sc query spacedeskHookKmode
- check if the result shows "service does not exist" or if it's there and status shows "Running" or "Stopped".

Yes, I've updated the OS from Win 7 to Win 10 almost one year ago. For the sc query result please refer to the attachment. The service status is Running.

I also uninstalled the VNC and deleted the VNC mirror drive, the only display adapter is GTX 1070, but the problem still exists.

The spacedesk worked on previous windows 7 systems.

Yes, the spacedesk works on previous windows 7 systems quite well.

Hi @sunnyboy0030,
Thank you very much for verifying.
It seems that the old driver was not removed and continue to run after your Windows 10 upgrade.
Our old spacedesk Windows 7 driver (spacedeskHookKmode) should not be there and this causes the problem in the current spacedesk Windows 10 driver (spacedesk Graphics Adapter).

Could you please try to run Command Prompt as Administrator, then type the command: sc delete spacedeskHookKmode ,then reboot your primary machine.
After that, try to connect again the spacedesk viewer app it should work now.

Looking forward to your feedback.

Hi Lea,

Thank you for your effective solution. After running the sc delete spacedeskHookKmode command and rebooting, the spacedesk works again. Thanks a lot!

Hi @sunnyboy0030,
Thanks for the feedback.
We are glad to hear that spacedesk is now working on your side.
In case you encounter other issues, just let us know.
