You can download a trial version here: http://training.trivantis.com/2005trials/LectoraENT.exeI would strongly encourage that you get the 2007 version though as at the end of this year, we are dropping support for the 2005 version. In addition, the technology has greatly changed and AICC/SCORM content created with the 2005 version will require that the end user has Java enabled in their browser, which can lead to a slew of problems. In 2006, the javascript title manager was added to fix this.You can still open titles created in older versions of Lectora with a new version (2007 will open a 2005 title). The only issue would if the title is saved using the 2007 version, it cannot be opened by the 2005 version.
