How to find out what the program installer is made of?

Question

Installer

Hello.
I downloaded the game client, and there is an installer, an installer that looks like a normal
Install 5-7 mb
Files in the .bin archive
At startup, the visual window is changed, and with only one field (specify the installation path) and at the bottom the "install" button
As clear and beautiful as possible .
The question is how to find out what or how this install was assembled?

Answer 1

It is quite possible that this is a regular self-extracting archive.
Done through WinRar, but in your case, most likely done through NSIS.

Answer 2

I would look at the properties of the files, as a rule there are links to the manufacturer. If not, then I would look in the notepad for the lines in the file, at the very beginning and at the end.

Answer 3

In some cases, it is possible to determine by the inscriptions and pictures, by the properties of the file, but here are the features that I know about:
1 - Inno Setup - the ALT + SPACE menu will be available there you can read
2 - NSIS - usually stands out for its appearance if the developer did not bother
As an option You can try to find out by enumerating the keys of a silent installation:
You read which keys for a silent installation NSIS uses and try to make a silent installation, if it did not work out, you read about the Inno Setup keys and so on. But there is one thing - silent installation may not be implemented in your installation file.

Answer 5
