Underrail not launching

[RailNomad]

I just downloaded and unzipped installer from http://www.indiedb.com/games/underrail/downloads/underrail-alpha-demo-v041 and ran the .msi file. Choosed to install to my new drive  at E:\Program Files (x86)\Underrail Alpha Demo instead of the suggested C:\Program Files (x86)\Stygian Software\Underrail Alpha Demo

Choosed to install "Just for me" instead of all users.

Running Windows 7 64-bit

Now when I click Underrail icon on the start menu, nothing happens. If I run underrail.exe from command line, I get no error messages, but nothing happens.

I remember installing and uninstalling Underrail on this machine before, though I'm not 100% sure.

Perhaps it's the install location that is causing problems or "just me" setting?

Hmm... uninstalled it and installed into default location with default settings. Still no luck.

(Might be the divine guidance preventing me from putting time into this at the eve of entrance exams, though.  )
