How do we use this tool?

Hi,
I tried using MemAnalyzer, but cannot get it to work? Which .elf files does it work on? I was under the impression that it would work on the .elf or .bin file generated through Arduino IDE for ESP8266. This is what I get (windows 7, esp8266 empty example using arduino IDE)

MemAnalyzer.exe       c:\Arduino-Build\sketch_jan01a.ino.elf       C:\Arduino-Build\
Caught Exception The specified executable is not a valid Win32 application.

Why is it expecting a Win32 application? I went through the code for MemAnalyzer. It is attaching the input file to a new process and then running it, and then analyzing its various sections. How is this related to ESP8266? Thanks.
