All software are available for FREE. On CosmoteBooks, there is a specific indication, for all Adobe DRM protected books. If you read on e-readers, consult the manufacturer's instructions in order to verify that your e-reader opens Adobe DRM protected books. The vast majority is compatible. Amazon's Kindle is NOT a compatible device.
