I didn't go through the motions because I went through that in the beginning and I ended up being told by Quickbooks support team I needed to create a new login on my computer (not the program) which was a lame suggestion and made it unusable IMO.
However... I installed it again where I wanted it in the first place but, unlike the first time when I first purchased it, it worked. IDK if it was because I now am running High Sierra or what but it didn't require that I create a new computer login like before. It allowed me to install the latest updates and after expanding my most recent backup, I was able to get that up and running too. Too bad this version is now out of date (it's the 2016 version) but I never wanted it to connect to my bank in the first place so I'm OK with it.
I'm not too excited about trying any new upgrades until it's been out there a while. I don't like being the one who works out the bugs in new programs. Not gonna do the online version either. Quicken is now dead to me for that very reason.
