I've installed 737 600/700 and 800/900 on a WIN2K PRO OS. All seems to work properlyWhat doesn't work?I mean: in which sense PMDG products are not fully compatible with WIN2K Pro?ByeFabrizio

Its not they're not compatible, its the fact we won't support any other OS than Windows XP.

.... and it works very well with 98SE too.

.......... in fact 98SE does it faster.

During the beta, 98SE had issues. I believe 800/900 may need some additional "Tweaks" or may not work at all in 98SE.
