Hi guys.

I thought it would be good place to ask - I'm trying to run old Big Times Software Flight Commander 2 under Windows 7, but I got generic "can't run under 64-bit operating system" error message.
Can you point me in some direction or give hints how to launch it?

Thanks in advance.

It's a 16-bits program so it won't run under a 64-bits OS.
You have to use a 32-bits OS. Using a virtual machine may help for this, like the Windows XP mode from Microsoft, or Virtualbox and the like.

I used to play it with Windows XP mode. But it doesn't work anymore using AMD's virtualization technology activated in the bios (SVM mode).

Alternately, you could cram it into Wine. Wine likes running crufty old 16 bit programs.
