    Hello.

    I’m getting “Authentication error, please try again” error when trying to change server settings on local machine. Also I can’t close app and reinstall didn’t help. nxerror.log contains many errors like “Process: WARNING! Process creation failed for ‘C:\Program Files (x86)\NoMachine\\bin\\nxexec’. 13472 15876 12:07:53 282.718 Process: WARNING! Error is 740 requested operation requires elevation”. NoMachine free v6.8.1, Windows 10.

    Please, open the folder %PROGRAMFILES(x86)%\NoMachine\bin\, right-click on file nxexec.exe, choose “Properties” from the context menu, select the Security pane and verify that users have permission to Read and Execute.

    If you prefer the command line, run a Command Prompt and type the command icacls "%PROGRAMFILES(x86)%\NoMachine\bin\nxexec.exe"

    I checked rights and users have these permissions.

    I get the same behavior if “Run this program as an administrator” is checked in the Compatibility pane of nxexec.exe. Is it your case?

    Would you send to forum(at)nomachine(dot)com:

    • The output of command icacls “%PROGRAMFILES(x86)%\NoMachine\bin\nxexec.exe”
    • An image of the Security pane of nxexec.exe
    • A zip archive of folder %USERPROFILE%\.nx
