Force a url to open in IE from chrome without command process warning message

Question

My requirement is to open few urls on IE browser on cliking their links. So i have followed the below code to set the registry

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Classes\ie]
"URL Protocol"=""
@="URL:IE Protocol"

[HKEY_CURRENT_USER\Software\Classes\ie\shell]

[HKEY_CURRENT_USER\Software\Classes\ie\shell\open]

[HKEY_CURRENT_USER\Software\Classes\ie\shell\open\command]
@="cmd /c set url=\"%1\" & call set url=%%url:ie:=%% & call start iexplore -nosessionmerging -noframemerging %%url%%"

I am able to launch the IE window from chrome but with a warning message "Always open these types of links in the associated app" as below

Chrome warning message

I have seen following links. But couldn't get away with this warning message.

I believe /c will do the trick to get away the warning message. But it's not working for me.

Is there any command line options to suppress the warning window?. Any help would be appreciated.
