Question

Hi I am trying to create a registry key in C++ but I keep getting the error 5 which googling told me it was access denied but I don’t know to do get the correct privileges. I’m using windows 7 and here’s my code. Thanks

HRESULT hr = S_OK;
UINT er = ERROR_SUCCESS;
LPWSTR szValueBuf = NULL;
char szProductName[MAX_PATH];
LPSECURITY_ATTRIBUTES lpsa;
HKEY hOrchKey;
DWORD dwOpenStatus,
      dwType;
char szProuductKey[MAX_PATH];

hr = WcaInitialize(hInstall, "CreateProductKey");
ExitOnFailure(hr, "Failed to initialize");

WcaLog(LOGMSG_STANDARD, "Initialized.");


if (!(lpsa = default_sa()))
    return FALSE;

hr = WcaGetProperty(L"PRODUCTNAME",&szValueBuf);
ExitOnFailure(hr, "failed to get Product Name");

wcstombs(szProductName, szValueBuf, 260);

sprintf(szProuductKey,"SOFTWARE\\Company\\%s",szProductName);

// Open the registery Orchestrator key
if (RegCreateKeyEx(HKEY_LOCAL_MACHINE,
                szProuductKey,
                0,
                "",
                REG_OPTION_NON_VOLATILE,
                KEY_QUERY_VALUE,
                lpsa,
                &hOrchKey,
                &dwOpenStatus) != ERROR_SUCCESS )
    return FALSE;   

OS_RegCloseKey(hOrchKey);
return TRUE;
