Rolf:

Where did you get the WebWorks (as distinguished from the newer ePublisher Pro) installation program?

As a former and generally less than impressed customer of Quadralay, I recall that the installation program shipped on the CD-ROM for one of the last releases of the older WebWorks Pro was defective the day it was delivered.

The solution was to go to the Quadralay Web site, complete a cumbersome registration process so as to acquire access to the support portion of the site, and download an updated installation program.

At this point, however, I don't believe that Quadralay will today retroactively support any versions of WebWorks Pro. That in turn may mean that you might not be able to acquire the updated installation program.

As Art suggested, I would recommend contacting Quadralay. Good luck -- they're not as far as I know anyone's favorite vendor...

Cheers & hope this helps,
Riley
