I cannot get Palm Desktop 4.2.1 to install on either of two computers using Panther. One had an old 4.0 on it, the other was a fresh install. They both fail the same way; hotsync manager doesn't install, then the applications won't work because the shared libs are missing.
Searching on the Internet, I notice many folks have had these problems, but all the solutions described are completely unworkable (such as logging in as root - the install fails the same way anyway, but now all the files belong to root). It appears to me that nobody should be able to install Palm Desktop under Panther.
