I believe I downloaded the The Witcher 2: Enhanced Edition install files during the 22/04/2012 according to Windows Explorer (Originally thought I got it much closer to release date) and was wondering if the game installer was ever updated/optimized at any moment after that date and if it is worth re-acquiring (Is it faster at installing, does it no longer Verify the Install Files twice, first without admin rights then a 2nd time with them? etc.)

It's kind of a pain and takes forever to install the game from the install files I've downloaded previously from GOG so I'm simply wondering if they ever got updated/replaced with a speedier installation process so that future re-installs of the game can happen faster.

Edit: My existing installer consists of 9 files totaling roughly 14.9GB in size.
