[Scilab-users] Compiler needed in V5.4.1

[Michael J. McCann]

New to Scilab 5.4.1 on Windows XP SP3 (also have 64bit version on Windows8)
Trying to get Modelica (Electrical) components working in Xcos
Scilab complains that a compiler is needed,
Windows "Add Remove Programs" lists Visual  C++ 2005, Visual C++2008 as 
being on system.
findmsvccompiler() says 'unknown'
haveacompiler() says  'F'

So what am I doing wrong or what should I do?
Mike.
