If you install the trial version of Adobe Captivate 6 then be aware that anything you publish from this will expire 30 days after the project creation date.
This is a rather big change (which haven’t been very well communicated by Adobe) and can cause major headaches for you. In Adobe Captivate 4 this 30-day expiry for projects created with the trial version also existed, but it was removed in Adobe Captivate 5 and Adobe Captivate 5.5. Therefore many people falsely think that it is not present in Adobe Captivate 6, but that is unfortunately not the case.
Furthermore there are also reports of people installing the trial version of Adobe Captivate 6 and later upgrading to a paid version experiencing expiring projects. Apparently this can still happen if you have started a project with a trial version and then unlocked the trial version to a full version by entering a serial number and published your project from the full unlocked version. Therefore it would probably be a good idea to completely uninstall the trial version of Adobe Captivate 6 and then reinstall it again using your serial number and republish the content.
