Hold your horses lads. 
IDM is not easy to do, there are several issues that needs to be resolved but consider it work in progress.
I really don't think anyone gets it perfect the first time. 
So lets instead give some feedback about what does and what doesn't work. 
And yes, it's Inno. 
 
Cheers.

You don't understand.
Why do you fiddle around with uniextract?
If you had followed the two relevant topics here, you would have known that it has been made with Inno.
 
Furthermore, this installer appears to be packed with a non-vanilla Innosetup packer, cannot be extracted by means of uniextract or better said innounp.
If the author of the repack makes available his sources to you is another thing.
 
Cheers.
