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?
