Will SmartPLS 2 still be available in the future?
Yes, but official support for SmartPLS 2 ended on 31.07.2014. Nevertheless we will provide SmartPLS 2 downloads and free-of-charge licenses on request.
See this page for a comparison between SmartPLS 3 and SmartPLS 2. E.g. SmartPLS 2 is based on Java 6 which is no longer supported by Oracle and has serious security issues.
If you like to use the latest advances in PLS path modeling, we strongly recommend you to upgrade to SmartPLS 3. If you plan to use SmartPLS on a Mac or to install and run it in computer labs, SmartPLS 3 is definitely the best choice.
