good that you're asking today and not last week: today the answer is positive. ;-)
I just managed to review the contribution by Ross, user in Australia, for the NSIS installer.
with that, I just published release 1.0.85.
if you prefer a self-contained portable installation, ghini on a stick, and if you can wait a couple of days, I have slightly adapted the software and am about to publish it in the next 1.0.86 release. Starting 1.0.86, you should be able to run ghini from a USB stick, along with its databases, move the stick to a different Windows machine, and all should just work.
if you don't need running on a USB stick, you can grab the Windows installer for 1.0.85, here:
let me know if all goes as smooth as I describe.
ciao,
Mario
