im also having the problem, i had it downloaded and in my taskbar but then the icon turned to a blank page and told me the same thing. i tried redownloading it two times but it would just delete the exe file or give me a popup that it has unwanted files or is a virus and doesnt let me do anything. (im on a windows laptop!) EDIT: i followed the antivirus errors stuff, and it worked! i highly reccomend it! thanks clangen team :D
