There are only two required fields in a .ZAP file, an Application Name (called a Friendly Name) and a Setup Command line. Other information is optional. The .ZAP File begins with a title line consisting of the word Application inside single Square Brackets (()). Underneath this come the entry fields, the two Required fields being FriendlyName = "''Name''" and SetupCommand = "''\\Server\share\setupfile''". You can also add Optional entries, such as DisplayVersion = and Publisher =. Note that DisplayVersion and Publisher do not require Quotation Marks around the variables.
