CreateProcess inside NPAPI plugin

[bula]

Hello
I am trying to create a function inside a NPAPI plugin that will execute a command received as an argument using CreateProcess...
I managed somehow to convert from const char to LPCWSTR, the plugin loads in the browser but when I try to call the function in breaks and it displays Plugin cannot be loaded... ( javascript error )

Bellow is the code, the plugin is built using FireBreath

// Method run
FB::variant HarrisonRunCmdPluginAPI::runCommand(const char command)
{
    STARTUPINFO startupInfo = {0};
	startupInfo.cb = sizeof(startupInfo);

	PROCESS_INFORMATION processInformation;
	
	LPCWSTR cmd = (LPCWSTR)command;

	// Try to start the process
	BOOL result = ::CreateProcess(
	  cmd,
	  NULL,
	  NULL,
	  NULL,
	  FALSE,
	  NORMAL_PRIORITY_CLASS,
	  NULL,
	  NULL,
	  &startupInfo,
	  &processInformation
	);

	if(result == 0)
	  return("Could not create process");
	else
		return true;
}

if I hardcode an exe file like "c:\\windows\\notepad.exe" it works with no problem...

Can someone tell me what I am doing wrong...

Thank you
