Also I detected something strange about this file.
Using MGInstaller from 2018 or 2019 to detect it's version is NOT possible to detect it as original installer, only if you use a MGInstaller from 2014 or 2015.
However the same MGInstaller from 2018 or 2019 are able to scan the same information from previous versions of the software for example 10.1c or 10.2c or 10.4c or 10.5 or 10.6 or 10.7 ... Very suspicious why cannot detect 10.4 itself ???
I am not saying is fake file but it's suspicious why only the year close to it was able to detect rather then more advanced installers while more advanced installers can detect even previous and future versions but cannot detect this specific !!!
What do you mean? Are you just announcing or do you want me to check it the content? IN that case I already have this version however let me know the hash of the file inside and I let you know if was untouched or not.
