Attempting to use MsiEnumRelatedProducts with various input is constantly returning only ERROR_INVALID_PARAMETERS for me. The documentation doesn't give any details on what the source of the invalid parameter could be but I've tried many different options. Currently I have this code below to demonstrate the problem. Replace the with a valid upgrade guid.

int _tmain(int argc, _TCHAR* argv[]){const wchar_t* upgrade = L"812D9038-YOUR-GUID-B2EB-64F4E0B3FB3D";wchar_t 产品[39];DWORD 索引 = 0;

int _tmain(int argc, _TCHAR* argv[]) { const wchar_t* upgrade = L"812D9038-YOUR-GUID-B2EB-64F4E0B3FB3D"; wchar_t product[39]; DWORD index = 0;

switch (MsiEnumRelatedProducts(upgrade, 0, index++, product)) {
case ERROR_SUCCESS:
    wcout << L"ERROR_SUCCESS" << endl;
    break;
case ERROR_NO_MORE_ITEMS:
    wcout << L"ERROR_NO_MORE_ITEMS" << endl;
    break;
case ERROR_BAD_CONFIGURATION:
    wcout << L"ERROR_BAD_CONFIGURATION" << endl;
    break;
case ERROR_INVALID_PARAMETER:
    wcout << L"ERROR_INVALID_PARAMETER" << endl;
    break;
case ERROR_NOT_ENOUGH_MEMORY:
    wcout << L"ERROR_NOT_ENOUGH_MEMORY" << endl;
    break;
default:
    wcout << L"DEFAULT" << endl;
    break;
}

}

推荐答案

尝试将升级代码括在大括号中，使其看起来像 {GUID}.

Try enclosing your upgrade code in curly brackets so it looks like {GUID}.
