I use Mint 17.1 and our Quicken Home works well and is stable. I use PlayOnLinux to get it to run and there's been no problems at all. You might give it a shot. Or Try CrossOver from CodeWeavers.
You could also use the free Oracle VM VirtualBox to run a Windows OS and do whatever you need with QuickBooks. I use VirtualBox on my Mint to run XP for a number of Windows Programs. Games and such.
It has been several years since I last tried PlayOnLinux / Wine / CrossOver. It was not working very well back then. Perhaps things have changed.
I’ll take a look. Thanks.
