I did an archive and install of Panther on my PowerBook to upgrade from Jaguar. After this, HotSync was broken. I re-installed the Palm Desktop software and then iSync 1.3 and this fixed the problem of Hotsync failing to launch, but syncing was still broken.
After much poking around on the 'net, I finally found the fix for my problem. Apparently, an essential piece of the Hotsync software was not moved to the new system during the Panther install. The PalmBladeConduit.bundle was in my previous system folder but not in my current (i.e., Panther's) system folder. To fix, I did this:
Note: the above is a one-line command entry in the terminal. Remove the line breaks and the indent spaces -- such that the text comes right after the "/".]
% sudo cp -Rp /Previous\ System/Previous\ System 1/System/ Library/SyncServices/PalmBladeConduit.bundle /System/Library/ SyncServices/PalmBladeConduit.bundle</code>
