I have both a Windows 10 machine and a Mac. I tried to install 8.1 on the windows machine and I got a Trojan horse virus warning (7.1.80 installed fine) and my antivirus software prevented the install. On my Mac machine it installed OK. Is this a compatibility problem with the antivirus software or is the program corrupt?
Also on my Mac I now have a .sce and a .scex version of every one of my scenes. Should I delete the .sce scenes?
