Customer Downloads

TN3270 Plus has been enhanced so that a License Code valid for a particular release (for example release 3.2) will also work on the next release (for example 3.3).

So if you have a License Code for the immediately prior version you can just download the current version from www.sdisw.com/download.aspx and apply your License Code when you start it.

Releases more than one release prior to the current release are not supported, so if you need a replacement for any version older than that you need to order an update to the current version.
