So I figured out how to download the trial just by googling a solution that let me bypass the installer and just use the direct download link. I'm surprised no one mentioned this. I wasted a day trying to download it using the installer. This forum sucks. :/
I guess you download from below link :
Adobe CC 2015 Direct Download Links: Creative Cloud 2015 Release | ProDesignTools
That is temporary fix, but it is very important to fix the issue with CC app. it not only just installs the application , it also detects necessary updates from time to time automatically , whenever there is change in OS like Windows or Mac OS , respective patches updates are released .
but you can also download those patches from same direct link , but you will need to check website frequently to check for available updates or you can also check from Apps Help menu.
Trust me , you have no Idea how helpful this Forum is for people. Feel free to ask if you need further assistance , we will be happy to assist you ..
