Sorry, I'd missed where you said this before.  For some reason, it's not 
able to allocate memory.  The most obvious possible cause of this is that
there is no memory available.  I suspect this is not the case here.

Another possibility might be DEP (Data Execution Prevention).  I found
some possibly helpful information from this thread:

http://www.openeuphoria.org/cgi-bin/esearch.exu?fromMonth=4&fromYear=B&toMonth=6&toYear=B&postedBy=&keywords=dep

  Go to
  Control Panel
  System
  Advanced
  Performance -> Settings
  Data Execution Prevention
  Click "Turn on DEP for essential Windows programs and services only"
  And that is that, you must restart I think.
  DEP catches Euphoria because the call_back actually just runs code, in
  memory that doesn't have execute permissions, but the processors never
  checked before now, turning it off makes it work still, but it really
  should be fixed, HINT HINT maybe all memory allocated in euphoria
  should have execute permissions by default, that would fix it.

Another poster in the thread noted that he only had to add exw.exe 
(you'll also want to add exwc.exe) to the whitelist.

The errors that the other person was getting aren't exactly what you're 
seeing, so this might not be the same problem that you're getting.  Have
you been able to run other euphoria programs?  Try going to 
%EUDIR%\DEMO and run:

> exwc sanity.ex

...and please let us know what happens.  This is a program that tests most
euphoria functionality, so if there is some other problem, sanity.ex will 
hopefully help us to diagnose it.
