I found this open source tool innounp
that is able to extract any files from MyDefrag's install file, its a commandline tool but there is instructions how to integrate it with Far Manager
and Total Commander
on the site.
This tool makes it possible to extract the 32bit(MyDefrag,2.exe) version of MyDefrag on a 64bit(MyDefrag,1.exe) Windows or vice versa.
Hopefully using this tool don't violate MyDefrag's license
