I'm having a similar issue (and I have scoured the web looking for answers after being on the phone and on hold yesterday for 3 hours).
I'm trying to update InDesign with the Digital Publishing Suite. Adobe tech support sent me a link for a direct download, but when I try, I get the sam message all these folks are getting.
I'm on a university laptop and I talked with our IT people, who told me they hadn't suppressed anything. The CC version I'm using is my own copy, not university-licensed. Our IT guy suggested I uninstall the CS6 version they had installed earlier on my laptop and then restart it. I did, but I got the same results.
Please help (I realize this isn't a PS CC question, but it's the same problem, it seems)
Please check your private messages, I have provided the details of files to be removed which suppress updates.
If these files are present, Do ask your admin to either not suppress updates or run update package so that you have the latest Ps on your system.
