How to correctly add "Open Cmder" Here in the context menu of Windows?

I've installed Cmder with chocolate: https://chocolatey.org/packages/Cmder

and I would like to have a shortcut in my context menu to open cmder in the current directory. I followed [the official wiki]:

Windows registry editor version 5.00

[HKEY_CLASSES_ROOTDirectoryBackgroundshellCmder]
@ = "Open Cmder Here"
"Icon" = ""% CMDER_ROOT% \ icons \ cmder.ico  ", 0"

[HKEY_CLASSES_ROOTDirectoryBackgroundshellCmdercommand]
@ = ""% CMDER_ROOT% \ Cmder.exe  "/ START "% v  ""

(https://github.com/cmderdev/cmder/wiki/Context-menu-integration) but even if the icon to start Cmder appears in the context menu, however, it generates an error in a message box saying:

Windows can not access the specified device, path, or file. You may not have the appropriate permissions to access the item.

The path of the Cmder executable is in: C: tools Cmder Cmder.exe

The environment variable seems to be going well:

echo% cmder_root%
C:  tools  Cmder

I can not really understand what's wrong here, an idea?
