Seriously, you can't run it on Windows NT, but the What's New for ASE 15.7 SP100 (Adaptive Server 15.7 SP100 Feature and Platform Matrix)
says Windows x86 32bit (http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.infocenter.dc01718.0512/doc/html/mza1364494783680.html) will work. I don't know about you, but saying "Windows x86 32bit" or "Windows 64bit" is pretty vague. Are we talking Windows XP and higher? 2000 and higher? Vista? Server 2003 or 2008 or 2012?
Anyways, it is good for a laugh
