cant connect  

and how to attach that dxdiag file

Hi @harry,

Attach option should be visible on your side after your second post.

To further analyze this issue, please download the spacedesk diagnostic script here, then extract it.
https://www.dropbox.com/s/ilm5em35h0ygsfm/2020_spacedeskDiagnosticTool.zip?dl=0

Inside you will find spacedeskDiagnosticTool.cmd, just right-click it then run as administrator.
This script will start a debug view app to capture spacedesk debug traces.
On step 5 it will prompt you to reproduce the issue (by connecting the viewer app and wait for the issue to happen), make sure to do this before pressing any key to continue.
After the script is done, a folder will be created on the same folder as the script file which contains various log files that we need for analysis.
Please right-click it -> Send to -> Compressed (zipped) folder, then attach the *.zip file on your next reply.

here is the zip

hear is the full folder 

Hi @harry,
Thanks for sending the diagnostic logs.
Based on your dxdiag, you have splashtop software currently installed on your machine.
Please remove this software, reboot your primary machine then try again with spacedesk.
For more info, please check Incompatible Display Hook Driver Detected chapter in our user manual https://spacedesk.net/user-manual/.

still facing the problem 
this is new file 

Hi @harry,
Thanks for sending your new diagnostic logs.
Unfortunately the DebugView.log is empty.
And we can still find the splashtop driver (LuminonCore IDDCX Adapter) on your dxdiag file.
Did you already try to uninstall it? Did it finish the uninstallation properly?

i deleted the splashtop from pc through control panle and also the driver now still nothing 
this is after i deleted. can you still find it.

and idk why but it is still empty the view log

Hi @harry,

Could you please run Command Prompt as Administrator then type the following commands:

sc query lci_proxywddm <enter>
sc query lci_proxykmd <enter>

if the status shows running or stopped then type this command:
sc delete lci_proxywddm <enter>
sc delete lci_proxykmd <enter>

After executing the command/s, please reboot your primary machine then try again with spacedesk.
