2) Choose SOHO Organizer > Preferences
3) Select the Sync preference pane
4) Click Unregister SOHO Sync

STEP B. Quit the background helper applications.
SOHO Organizer uses several helper applications to provide services when it's not running. The helper applications run in the background so you don't normally see them running. You'll need to quit these helper applications before you can delete the SOHO Organizer applications. Here's how:
1) Launch SOHO Organizer
2) Choose SOHO Organizer > Helper Applications
3) Click Quit Helper Applications
4) Quit SOHO Organizer
STEP C. Uninstall the software.
To completely delete SOHO Organizer and remove all files related to it, please drag the below items to the Trash and then empty the Trash. The path for each item is provided.

This path is different from "/Library" which is the main Library folder at the root level of your hard disk.
