Microsoft greed is affecting this release as well. Even though our signing certificate should long have been whitelisted, the annoying "SmartScreen" dialog saying "Windows protected your PC" (blah blah) is still there. To get past it, please click the "More info" link and next the "Run anyway" button. I'm afraid we all need to train Windows SmartScreen some more for a while (sadly). The more people deem it OK, the faster this dialog will go away for everyone (or so MS keeps saying).

SmartScreen -> More info SmartScreen -> Run anyway

Please tell people about it, like and share it on Facebook and/or Twitter, post it on forums, reddit, etc. Practice safe and honest computing and stay away from cracks and keygens. Your help is appreciated.
