It looks like Webroot is blocking the application by sending out a false-positive alarm . This often happens with ren'py games because most anti-virus pick up ren'py games as a virus. Some antiviruses auto-delete any exe files that aren't in their directory. I'd suggest disabling your anti-virus software- you should turn off the antivirus temporarily or mark it as "safe," then try downloading it again. When it claims a ren'py game is "malware" it is actually breaking third-party software.
