This seems like a simple question but I cant find the answer. Do I need to install bitcoin core, download the 390GB block chain for Armory Wallet to work? I, like many others are stuck on Preparing Database in offline mode and the solutions Ive read seem absurd having to add special parameters to config files or redefine file paths. The app should work out of the box, but it doesn't?  Will Armory work without bitcoin core installed?
