Similarly, I purchased, downloaded and installed Quicken 2016 yesterday from amazon.com.
It wouldn’t get past the Intuit ID creation, so I couldn’t launch it. This was bad because before the Intuit ID process, it deleted my previous version of Quicken.
It got worse because Intuit tech support is not open on Saturday. Fortunately, I found the Chat and a guy there helped me. Turned out that the version of Quicken 2016 that you download from amazon.com is not the most recent. He directed me to the update and everything worked like it should.
I am still in transition after having a hard drive failure. The computer service guy put in a new drive and loaded Win 10 for me, but without a verification key. He said my Win 8 key would work for Win 10, since it was an upgrade to it.
Got home and was wading through restoring my stuff on the new drive when I saw my OS was not authenticated, locking me out of stuff. Where was the key? Well.... The Win 8 key didn’t work.
So I called Microsoft who put me through to a tech who said, “Reload Win 8 with your Win 8 key, then update to WIn 10.” Aargh. But it worked.
Then I loaded Rollback, when blew the system out the door and made me realize I had no way to safe start, as Win 10 has moved that function. I futzed around and blundered into the “repair” system and found a means to system restore without being at the main GUI.
Like I said, I’m still cleaning up the mess.
