Compilation Error with VC++ 2005 Express

[Lapin]

Hi,

When I try to compile log4cxx_vc7 or even QuantlibXL I get the following error message:

fatal error C1083: Cannot open include file: 'windows.h': No such file or directory

I have no problem compiling Boost or Quantlib standard.

Any thoughts on the subject?

Regards
