ok most planes ive downloaded using windows 7 are appearing just fine,,,,i did find a neat tool called j zip from cnet that makes things easy it actually eliminates many steps and eliminates dragging and dropping which can be done as tested,,and isnt a pay for software program like winzip,,,,,and for anyone using win 7 and did a clean install..you will need to find and remove the old ipacs folder from the old windows folder,,or you will get errors and most likely not be able to run .
