Apart from "me too", I have a couple of observations to offer.
I got the VISEdata error immediately as download of each individual component finished. The text in the installer window flew by too quickly to read, but the gist of it seemed to be a problem verifying the downloaded file.
The installer did not crash out at any time, and each time I restarted the download it resumed from where it left off. Thus, doing the "deluxe" download (8 components) required resuming the download 7 times. After the final component downloaded, installation went without a hitch.
For all those complaining about the lack of a complete download option, and having to make a network connection to reinstall/install on a different machine, there is a simple solution. Make the complete download once, save the install file, then install to other machines from the install file on your desktop. This worked fine on my PB5300 after downloading on my beige g3 after tranferring the installer over ethernet, and worked from a zip on another g3...the data does not appear to be machine-specific.
Another possible solution if you cannot connect with the online installer: use OTsessionWatcher to capture the address to which the installer tries to connect, then use anarchie or netscape to get the files. I didn't have to try this myself, so it may not work.
