Hi,I just installed Acc/SP2 and discovered that there is a Setup folder in the main FSX folder that with over 1GB of datafiles. Is this normal or is it a leftover from the installation?Ulf BCore2Duo X6800 OC 3.3GHz, 4GB RAM8800GTX, dual view 1920x1200 and 1280x1024Creative SB X-Fi (Gamer mode)Vista Home Premium 32, FSX Acc/SP2WinXP Pro SP2, FSX SP1, FS9.1

Hello Ulf, Acceleration backs up all files that are replaced - in case you decide to un-install Acceleration, it can then restore your FS to the exact configuration you had previously.Best regards.Luis
