For some reason, I am unable to install the Pure Ref 1.11.1 or the 1.10.4 installer from chrome. When I do download it, I get a warning from windows saying it protected by PC, and that the file has an unknown publisher. When I tried to bypass windows and just open it, I received an error that the installer integrity had failed. I am downloading all of this directly from the Pure Ref site. Please, someone help me! This is driving me insane.
