Ultimate Boot CD

I'm keep getting the following error. I'm not understanding how it doesn't see the file even though it is there.

Any help would be great
Thanks

UBCD2ISO: Creating bootable UBCD ISO image ...

(ERROR) Missing file 'mkisofs.exe'

Press any key to continue . . .

Before you type 'C:\ubcd411\tools\ubcd2iso\ubcd2iso c:\ubcd411 c:\ubcd411.iso' at the command prompt,
type 'cd C:\ubcd411\tools\ubcd2iso'
This changes the directory to 'C:\ubcd411\tools\ubcd2iso'. This is needed because windows searches only in folders that are included in the %path% variable (c:\windows and c:\windows\system32 folders ,...) and in the current folder.
Then type: ubcd2iso c:\ubcd411 c:\ubcd411.iso

If you want to run the command several times, you can create another batch script. (Open notepad, paste the text from the box below, go to File ==>Save As..., give it a name with .bat at the end, set the Filetype to "All files" and save it). Now you can make you iso just by double clicking on the file.

C:\ubcd411\tools\ubcd2iso c:\ubcd c:\ubcd40.iso
