Question / Problem
What is the difference between the Professional and the Personal Edition?
Answer / Solution
The Personal Edition has the same features as the Professional Edition, except that it cannot be used with Windows server operating systems, does not support scans of network shares which are part of a Windows domain, provides no command line options and no scheduled scans.
The Personal edition scans network drives if the computer it runs on is not part of a Windows domain and the remote system is not a Windows server. This enables customers of the Personal Edition to scan network drives in their home network, including NAS systems based on Linux and Samba.
