Hello,

I recently purchased Take on Helicopters a couple days ago on my old computer.it ran fine on that computer, but when I tried to play it on my new computer I get the invalid key code error on start up. I don't know how to enter the key-code since I cannot get into the game. BTW, im using steam.

Right click on the game in your Steam library. You should see the 'game key' option on the list. Enter this key on start-up. I don't know if Steam will let you play it on different computers though. It may be worth contacting their customer support.

You CAN play TOH on multi computer with Steam. My dad does on my account sometimes.. :o
