Hi there,
i've just bought an entourage edge and i'm trying to update it's software to the last revision but i can't manage to do that successfully.
I click on update now in the "edge preferences" menu and it check for the new version and download it but when the download is finished (and an icon in the upper bar say that) i don't know how to install the update.
if i click on "update now" at this point the check-and-download simply restart without installing the software.
I hope you can help me.
Thank you
