NOTES:

• If you are currently using version 1.5.3 or earlier, please upgrade to TalkingJava SDK 1.6.3.
• When you purchase a license, your registration code will be emailed to you immediately. You should use this code in the LicenseManager tool (which is part of the TalkingJava SDK) to validate your license.
• If you purchase a license you may download and install later 1.x versions - your license will still be valid.
• A Personal License allows you to use the JSAPI implementation and SDK only for personal, academic, non-commercial and non-corporate purposes. It does not allow you to re-distribute the non-trial runtime libraries with your application, but you may distribute the time-limited evaluation runtimes.
• A Professional License allows the JSAPI implementation and SDK to be used for development, on corporate server machines, or for distribution in a commercial product - please see this page for details.
• An Academic Site License - for universities wishing to have a large number of students program with the JSAPI as part of a course - please see this page for details.
