I have a game called City XL platinum' I am trying to install it on my computer which is a windows 7 with a new graphics card that i was told would run any game. I downloaded on my other computer which is a windows 7 laptop and it works just fine. I cant understand why it works on one and not the other. I get this message. "error decompressing data corrupted installer" ..what does this message mean and is it fixable? Hope you can help thanks !
