error C2440 cannot convert from char to TCHAR

Jeg har lidt problemer med min kode.

Får denne fejl:

error C2440: '=' : cannot convert from 'char *' to 'TCHAR *'

i linien:

pEnvCMD = getenv("COMSPEC");

TCHAR *pDefaultCMD = _T("CMD.EXE");
ULONG rc;

memset(&StartupInfo, 0, sizeof(StartupInfo));
StartupInfo.cb = sizeof(STARTUPINFO);

StartupInfo.dwFlags = STARTF_USESHOWWINDOW;
StartupInfo.wShowWindow = SW_SHOW;


if (hide)
    {
    StartupInfo.dwFlags = STARTF_USESHOWWINDOW;
    StartupInfo.wShowWindow = SW_HIDE;
  }

Args[0] = 0;

pEnvCMD = getenv("COMSPEC");

if(pEnvCMD){

  _tcscpy(Args, pEnvCMD);
}
else{
  _tcscpy(Args, pDefaultCMD);
}

_tcscat(Args, _T(" /c "));

_tcscat(Args, _tcsFunct);
_tcscat(Args, _T(" "));
_tcscat(Args, _tcsstrParams);

if (!CreateProcess( NULL, Args, NULL, NULL, FALSE,
  CREATE_NEW_CONSOLE,
  NULL,

  &ProcessInfo))
{
  return GetLastError();
}

WaitForSingleObject(ProcessInfo.hProcess, INFINITE);
if(!GetExitCodeProcess(ProcessInfo.hProcess, &rc))
  rc = 0;

CloseHandle(ProcessInfo.hThread);
CloseHandle(ProcessInfo.hProcess);

return rc;
