GUI vs Genie?

[DERoss]

Windows 7 Ultimate SP1 x64

Netgear N300 Wireless Router Model WNR2000v5

I have GUI Language Version V1.0.0.204.  Is that replaced by Genie (current version 2.4.48.0)?  Or are they distinct applications?

   Ever helpful, Netgear uses the name "Genie" for more than one thing.
Netgear routers have a web-browser interface called "Genie", and Netgear
offers application programs for various computers/pads/phones, which are
also called "Genie".

> I have GUI Language Version V1.0.0.204.

   Where did you get that datum?  If it was associated with a firmware
version number, then it's probably determined by the firmware package
which is installed on the router.  In principle, Netgear could update
the GUI Language subset of a firmware kit separately from the main
firmware subset, but I don't know if that ever happens.

   Which "Genie" is that?  Mac?  Windows?  iOS?  Android?

> [...] Or are they distinct applications?

   The Genie apps are apps.  The router firmware is the router firmware. 
Those items are largely independent.

The GUI Language Version is displayed in the Router Information box when I login to the router and select [Advanced > Advanced Home]. 

I am assuming from antinode's reply that the Genie that could be installed from the file NETGEARGenie-install.exe (version 2.4.48.0) that I found on the Netgear Web site is NOT for use with a router used by a PC.

   Ok.  That's tied to the router firmware.

   "I found on the Netgear Web site" is not a very helpful description
of where you found that file.  "the Netgear Web site" is a large place.
Perhaps:

   https://www.netgear.com/home/discover/apps/genie.aspx

   "NETGEARGenie-install.exe" is the installer for the Windows variant
of the genie app.  If you want a genie app for Windows, then that's what
you'd use to install it.  But those version numbers which you cited have
approximately nothing to do with each other.
