Can the Sigmaplot version 10 downloaded for free and used "forever" or is only a free trial possible? Many thanks in advance!
No, the version is not available forever because it's listed as trial version. This means you can download it from the official website and test it for a limited amount of time or forever with limitations. In most of the cases, the trial is limited to a certain amount of time.
