1. YES，the new vesion must decompress in a different directory.
2. Your method can work in theory, but you must stop the iVentoy service firstly. If the iVentoy service is running, then some files in the old directory are protected and can
not be overwritten. So if you forget to stop the iVentoy service and just decompress the new version to overrite the old release, then you will get a half updated version which
will not work OK. That's why I suggest my update method.
