Daylite Palm conduit 1.6.4 is not fully compatible with the Missing Sync software.
Please use the following procedure as a workaround to install the Daylite Piranha conduit.
_{(Please note that this is for Daylite 1.x users. If you are using Daylite 3, this article doesn't apply because this issue has been rectified.)}

1. Create two dummy folders in the following location HD -> Library -> Application Support -> Palm Hotsync -> Conduits. The folders are: Install Conduit & Backup Conduit
2. Install the Daylite Piranha conduit.
3. Open the Daylite Palm Sync preferences window (from the menu bar select Daylite -> Preferences -> Palm Sync) Place a check in the 'Enable Palm Synchronization' box: However, by turning on Palm syncing in Daylite, it moves the Piranha conduit to the correct location, but puts all of the Missing Sync conduits into a folder called, "Conduits.psdisabled"
4. Go back to the HD -> Library -> Application Support -> Palm Hotsync -> Conduits folder. Remove the Install Conduit & Backup Conduit folders
5. In the 'Conduits.psdisabled' folder, move the Install Conduit.plugin & Backup Conduit.plugin files into the Conduits folder.
6. You should now be able to perform a synchronization between Daylite and you Palm device using the Missing Sync software.
