Quicken Home&Business 2015 - Has flown the coop, everything is gone bc the program has been eliminated - for no reason

In addition to 3x's week minimum on C, I've backed it up to G:drive, (Seagate) and H:drive (thumbdrive). I also subscribe to Norton OLBU. I can "see" some of my very older files but I cannot access thm because the Quicken Program has disappeared - I can see huge backups and when I click on or type in file strings in different drives, it seems that I'm making progress, shew! , then nothing. I go nowhere. I've tried to reload the disk several times in D:drive. Yay. I click, Nothing.
I went into my backed up Financial Files in Norton, didn't open them just grateful that they were still there. i copied/downloaded the most recent ones pre-Amazon fake email to my hard-drive and shortcut to desktop --success- or so I thought until I later on I found error messages on desktop generated by Norton, "unsuccessful".
P.S. I don't know why all those smiley faces are there and I tried again using your suggestion which takes me to where I was going in my searches. Same thing, click, circling, nothing. then right click, open with ...quicken or quicken windows whatever that is, circling, then , nothing. Qw folder is there, but I cannot access it. I think I've been hacked.

I don't remember the exact date, it was between then and the day I wrote. I cannot even remember the patch but it keeps showing up, annoyingly so, as if I've never downloaded anything else Quicken before.

I thought about upgrading to Q.2017 but the complaints from other Users are unending. I'm on the Quicken Help email list and every day I have at least 25 complaints from users about 2017 versions. I also check Amazon for prices and everyone there seems to have unending problems as well - it rates 50% on the happy scale. Also, it won't be $75 for me, it will be twi$ce that for the Home & Business Edition and I was informed that if I downgrade to Delux or Premier or whatever I'll lose access to 20+ years of Quicken Business history. In the meantime, I've been trying everything to address these issues, seeing if it's a corrupted registry, malware, ransomware, virus, prior to that I restored to an earlier date in June. I hand't mentioned or perhaps I have, too tired to check, that my main email account is also screwed up. AND I've been getting constant error messages about my Drive being too low on Memory so I worked on that following Windows instructions hoping that if I removed any superflous files which I possibly stored on it by mistake, maybe that's all I'd need to fix things. Nope. Why ? Bc I I have been removing old Restore Dates backups all along which I now regret- Thanks to MS for that horrid advice- I did learn how to view what's on that partition, that's a plus and I did a cleanout of absolutely nothing because there was nothing stored that shouldb't have been. Re: my own backups , I backup my precious files in 3 places: NOLBU, & 2 external Hard drives. No I don't compress the files, why bother ? But I have asted an entire weekend (a month if truth be told) on this, I've worked around PC's long enough to know what to do. I've accomplished nothing other than *finally* received an Error message from my Quicken Install Disk from C: drive= Quicken has stopped working, go on line to get help". I'm swearing right now....it links to no online help. I really don't need a Free download of the Version I have as I have the disk so calling Intuit will only make things worse as it will cause the inevitible heart attack from frustration when I reach a 16 year old foreigner. It's one of two things at this poing : The PC was built in 2009, I was told by HP it was new on 8/2012 ; being that it's 2017 and the model was sold knowing that it had a "bad motherboard" I assume that my harddrive could be dying. there are other issues, freezes, I can't retrieve my Office Outlook email from my main email account- error says the server doesn't recognize my login creds.... Yet it retrieves Outlook email for the sub-email accounts - which makes *absolutely* no sense, it's the same damn server . Which then makes me think , once again, that I've been hacked. I have two choices: throw this thing out the window and upgrade to a new, not HP PC w/the no money in my bank; or perform a 4th factory restore with fingers crossed.
