Boot.txt not found in hiren

I wanted to combine the kali linux 2019.1 & hirens boot cd from official website
https://www.hirensbootcd.org/
as per documentation changing names and pasting it in the multicd folder i did ./multicd.sh
but the output was

Cleaning up - removing symlinks to files in current directory
Made a link named kali.debian.iso pointing to kali-linux-2*.iso

*multicd.sh 20190303
Extracting ISO images with mount; will build multicd; UID 0.

Note: No BootCD.txt in hirens.iso
cp: cannot stat '/root/MultiCD/temporary-mountpoints/hirens/HBCD': No such file or directory*

Even after downloading from official site why show this note???

What version of the ISO are you using? Mine is named HBCD_PE_x64.iso (md5: 07170465c2f892088b7a725306737715) and it seems to work.
