Oops! I missed the SP2 installation, and now it works. Thank you very much!All that remains now is to get the fps to a reasonable level. My specs are: AMD phenom II X6 processor 2,8 GHz, 64 bit win 7, 8 Gb RAM, AMD (ATI) Radeon HD 6950 2 GB. This should make FSX run like Niagara falls, but when in VC the fps are between 13 and 20. External limiter set to 30 and in FSX unlimited, tweaked cfg by Bojotes site. In default a/c as i.e the Extra I get up to 70 fps in outside view?! Anyone with radeoncard who can enlighten me to proper settings? Regards/Stefan
