I am trying to upgrade a 11c from 25.35 to 25.40. I have already upgraded the boot rom off the software delivery card. I have installed the new NTTK25AA Flash Rom and new memory. I then boot up off the delivery card and when I get to Main cabinet software installation, I choose # 2 (System Upgrade). Then select type of upgrade comes up and I choose # 2 (11c new software upgrade.) then I see 25.40 will be installed. Then I see select feature you wish to install comes up. I choose # 3 Enterprise Business. (this is what is on my key code sheet.) At this point I get (Error could't open file: c:/p/sl1/direct.rec) I can not go any further. Thanks in advance.
