The Chilkat License is a perpetual license that does not expire. However, the ability to update to newer versions expires when support expires. Chilkat will send a Renewal Notification email shortly before support expires.
New version upgrades are free while support is not expired. Renewing provides the means to stay current with the latest versions of Chilkat. If support lapses for more than 3 months, the license must be repurchased at the regular price.
The Chilkat components and libraries may be used on any number of computers or servers.
The license is royalty-free, meaning that Chilkat redistributables (DLLs and shared libraries) may be included with your application's deployment/installer packages.
of the type of license purchased, a Chilkat component can be
used in any number of applications, and can be redistributed
royalty-free with your applications to end-users.
Licenses are sold on a per-developer basis.

programming with the component.

"I'm currently a licensed customer and use the Chilkat FTP2 ActiveX. I wish to migrate the application to .NET. Do I need to purchase another license?".
Answer: No. Your unlock code is valid for all platforms: ActiveX, all .NET Frameworks, VC++ (all versions), GCC/Linux, Perl, Python, Ruby, Java, etc, Linux, Windows, and any other operating systems supported now or in the future. etc.
(Regarding a 1-Developer License) "If I leave the project and someone else takes over can he use the same license (i.e. license for one developer at a time) or not (i.e. license for a specific named developer only ever)?".
Answer: The license is actually for one specific named developer. The reason is because a new developer presents a new support load (i.e. might be asking the same questions again, or new questions) and it's the equivalent support load of 2 developers.
