@tesparza the file you are running doesn’t appear to be the installer. It appears to be a self extracting archive that contains the installer. Once you give it a path, it should place all of its install files there, including a DXSETUP.exe, which would accept /silent.
My suggestion is to either find a different version of the installer, such as an MSI, or to take the extracted files and create a snapinpack out of them.
