Norton keeps deleting my files

I've been having problem with a old simulator i've been using to play a game so i uninstalled it and downloaded the installer again.

problem is norton keeps deleting my file saying reputation is low (previously the updating was done by the program's automatic updater) so the file might not be downloaded often i think.

 

i'm now stuck with how to install the program on my com but i can't even download the installer thanks to norton.

 

would appreciate if there's a solution. thanks!
