Password protected Files while Extracting

[Cuttlas]

I tried to extract this setup (which is created by Inno setup) using Inno Extractor 7.3:

https://dl2.soft98.ir/soft/j-k-l/K-L...rar?1711629087

but when I try to extract a file, It will prompt me for a password!!!

The setup files such as the wizard images and iss file can be extracted but the files that should be installed can not be extracted and need a password!!!

I do not need to retrieve the password.

I just need to know how to make such an inner password-protected setup.

thank you brothers.
