Donwload and install the drivers for your laptop from acer, but your model does not have official Win 7 support. You can try the Vista drivers though http://us.acer.com/ac/en/US/content/drivers.

You should also install the full Win 7 version, the beta software is not supported by anything, although it won't matter much since your laptop does not have Win 7 drivers to begin with.
