How to download and install Symantec endpoint protection free trial unmanaged client for 64bit server

I’m trying to download a Symantec endpoint protection trial unmanaged client for our server which is 64 bit. I registered at the site and found a download, but I am getting the error when I execute that the file is not compatible with my operating system (64-bit MS Server 2008 R2 which I see is supported).Before I get to the download it clearly says“SEP Small Business Edition 12.1 (32-bit, 64-bit or Mac Client, and Management Console)”But when I get to the downloads there are no 32/64 bit options. Does anyone have a link specifically to a 64-bit version or have any other idea?!
