You can delete a Composer Solution Pack solution. Deleting a solution deletes the button and removes it from any page layout where it was added. All underlying reports, queries, and templates are not removed unless deleted manually.

To delete a Composer Solution Pack solution:

Before you begin you must have a Composer Solution Pack solution installed.
  1. Open the solution record for the solution you want to delete.
  2. Click Delete.
  3. When the confirmation dialog box appears, click OK.
