I have seen Novell have trouble with the update. I have on a couple of occasions had to install the Pervasive Workgroup Engine to a workstation with a big hard drive, copy the entire DBAMFG folder to the workstation, install the update, then copy it back.
If you are planning to sign up for the IS Tech Support updates once you have 2002.4 installed, I would be happy to help you with the update!
