Installation problems

[eMuNiX]

I'm trying to install OpenCASCADE on a Windows machine, I'd like to do some FEA work but we can't afford ANSYS. Installed the program no problem but it has some dependecies that I can't get to install. I have C++, QT, Tcl/Tk and Java installed but I can't get Tix to compile and I don't know if FLTK installed, if only Tix and FLTK had executables. At the rate this is going I will probably skip this idea and simply install CAElinux.
