I don't know your language but you can translate this (as I did your post).
You say that you have uninstalled and re-installed the game. Did you follow the procedures listed in the link below? Also, look up the game's minimum requirements and make sure that you have enough resources. Remember that if you installed Windows 7 on an older computer or laptop that had only 1 GB RAM or less, then the operating system itself will probably use most of this, leaving little for the game. This game seems to work best on systems with 2 GB or more RAM. It also requires halfway decent graphics, something a laptop oftentimes does not have.
AOE 3 requires some additional steps to work properly under Windows 7. You might wish to view this post.
