Won't let me add windows OS's

[devicemodder]

I am trying to use MultiCD to create an iso with windows 7 Ultimate, Windows XP service pack 3 and windows 98. I renamed windows 98 to win98se, and it throws a tags error, renamed win 7 ultimate to win7recovery.iso, and it just mounts the image and does nothing with it. and it doesn't see my windows XP iso.

Here's my terminal output when run:

ibm@ThinkPad:~/MultiCD$ sudo ./multicd.sh Cleaning up - removing symlinks to files in current directory

multicd.sh 20191102 Extracting ISO images with mount; will build multicd; UID 0.

Windows 7 Recovery Disc (Not open source) Windows 98 SE (Not open source - do not distribute the final ISO) touch: cannot touch 'tags/win9x': No such file or directory ibm@ThinkPad:~/MultiCD$

How can i get this to run properly? It also doesn't even create the multiCD iso file. All these iso files are 32-bit.
