Hi, may be it’s usefull for someone : I had the same warning message as Jansen Bailey mentionned before. I’m using a PC running Windows 10 Pro (latest release with all updates done) : when windows prompt the message warning ” beware !.. it may be a virus “, I have cliqued on the blue zone of the message ( Tell me more ) and then hit the button ” run anyway ” ( I can’t remember the exact message ) and Animation Paper is installing without any problem … I hope it can help everyone that wants to install Animation Paper on a windows machine !.. ( mine is running Win 10 Pro 64 bits )
