I presume that @My1 wants to keep different versions of the GlassWire installer and it saves time if the version number doesn’t have to be added manually.
You could do what many sites do and have the other sites link to a web page that automates the download process rather than having them link to the download itself, e.g. as Piriform do for CCleaner http://www.piriform.com/ccleaner/download/standard
You could also consider a self-extracting zip or other archive format that extracts the installer with the correct version number as part of the name.
