Honestly, I wouldn't waste your time if I were you. I have the E2 De-esser and, don't get me wrong, it's a good de-esser, but not nearly as nice as FabFilter Pro-DS or Sonnox Suppressor. Support for Eiosis has been non-existent for years - trust me, I've been trying to get them to respond to my emails re: will 64-bit versions ever be available and can I sell this plugin repeatedly over the past 2 years but have never gotten a response. I've given up, but if you can get one of them to reply to an email, ask them if they will allow me to transfer my license and you can have mine for cheap. But, seriously, check out FabFilter and Sonnox first - they're better, more intuitive, still get updated, dongle-free in the case of Pro-DS, and most importantly....available for purchase.
