The B777-300 gauge needs the file msvcr.dll copied to the main FSX folder (root directory) or the gauges won't work in FSX. Copy the Boeing777-300.gau to the main FSX gauges folder. No need to overwrite either one if already there. Some other updates include the 777-300 gauge, so you might already have done the above. Bob Chicilo. bchicilo@bell.net
