Files with an el8 extension are recordings of Electa Live sessions. These files can be played locally on MAC or Windows computers after installing the Electa Live 8 application.
The applications for each platform can be found here: http://www.support.e-lecta.com/Knowledgebase/Article/50049
On mobile devices (Android, iPad and iPhone) el8 files cannot be played locally. You need a playable link to stream from. To get a playable link, please contact your training organization.
On all platforms Electa Live recordings can be played online after visiting the Recorded Classes menu of your student (or teacher area).
