GOM ENCODER Setup fails to complete

Hi there,
I want to install GOM Encoder to modify some video files. I have downloaded the installer from the official website and it says that is corrupted. I downloaded it again and the same error appeared. How can I install the GOM properly ? Why I can’t install it, is because I don’t have installed the GOM Player which I don’t need ?
Thanks !

The installer you are trying to use is corrupted or incomplete.
This could be the result of a damage disk, a failed download or a virus.
You may want to contact the author of this installer to obtain a new copy.
It may be possible to skip this check using the /NCRC command line switch
(NOT RECOMMENDED).
