Hello, I've purchased a licensed copy of Wordworth 6 Office from 1996. However, I can't get the installation to work.
My setup is:
PowerBook 6.5
1200 MHz
735 MB RAM
MorphOS 3.15

After booting up, I open the shell, cd to english_products/wordworth_6, then do:
execute install_wordworth_6

After choosing "Expert User" at the installer, then "Install for real", then chosing the destination for the "Wordworth6" folder, it asks: "Do you wish to install the small font library?"
Whether I click "Yes" or "No", it bails out with the message:
"Sorry... an Error Has Occured!
MAKEDIR: Couldn't create directory
DOS Error Type: Cause of disk-.related error unknown."

The Wordworth6 folder has been created by the installer, though, but it is empty.
Logging the installation process to a file doesn't work.

How can I find out what went wrong and proceed with the installation? Any help would be appreciated.
