error PRJ0019 using Qt commercial with VS2005

Hi,

I'm new in the Qt programming, and I need some help.

I have a commercial version of Qt4.4.3 which i use with VS2005 professional edition.

When i tried to build my application I've got the following error message.

"Performing Makefile project actions
MAKE Version 5.2 Copyright (c) 1987, 1998 Inprise Corp.
Fatal: 'FORCE' does not exist - don't know how to make it
MAKE Version 5.2 Copyright (c) 1987, 1998 Inprise Corp.
Fatal: 'FORCE' does not exist - don't know how to make it
Project : error PRJ0019: A tool returned an error code from "Performing Makefile project actions" "

The application was made using the Qt4.4.3 Open Source version and when I build it with this version i have no problem.

Why do i have the error when i tried to build the application with the commercial version?

Apparently Borland products, either C++ Builder or Delphi, are in your path and mask access to MSVC
