When using AspPDF, this error is thrown: QueryInterface for IResponse failed: (followed by a reason) Solution This error usually occurs because of tight security settings in the HKEY_CLASSES_ROOT section of the registry. To fix the error, run Registry Editor and select the following key: HKEY_CLASSES_ROOT\TypeLib\{D97A6DA0-A85C-11CF-83AE-00A0C90C2BD8} From the Security menu, select Permissions. Add Everyone to the permission list and assign Full Control to the Everyone account. Make sure the setting propagates to the sub-keys as well. On Windows NT and 2000, you must run RegEdt32 to have access to registry key permissions. On Windows XP and newer, use RegEdit .
