Why is the value not being added to the registry?

Question

C++ / C#

void Utils::Autoload(string Name , string Path ) {
  string command = "REG ADD \"HKCU\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\" /V " + Name + " /t REG_SZ /F /D " + Path;
  system(command.c_str());

Answer 1

HKCU\\HKEY_LOCAL_MACHINE

It's kind of a strange combination. Must be either HKCU or HKLM, but not one under the other. Judging by the full name of the key, it should start with "HKLM\\SOFTWARE\\Microsoft…".
