I installed HS4 into my existing HS3 folder as instructed. During the installation an HS4 folder with 'Temp' sub-folder was created. Can the HS4 folder be deleted? If so, can I then rename the legacy HS3 folder containing the HS4 software to "HS4"? It's all just housekeeping but having HS4 in a folder named HS3 is annoying.
