The fully-functional Chilkat components are always downloadable at http://www.chilkatsoft.com/downloads.asp
Chilkat components and libraries are unlocked at runtime by calling the UnlockComponent or UnlockBundle method once at the beginning of a program. A 30-day trial automatically begins if an invalid unlock code is passed to UnlockComponent. For example:Dim glob As new Chilkat.Global
glob.UnlockBundle("Start my 30-day Trial")
or...Dim mailman As new Chilkat.MailMan
mailman.UnlockComponent("Start my 30-day Trial")
When a license is purchased, you will receive an unlock code that should be passed to UnlockComponent.
