got a prb with this c compiler from bloodshed?

[Knightmare]

i downloaded this c++5 beta version from http://www.bloodshed.net/dev/devcpp.html to my laptop having windows vista. i run the setup program and after installing and opening the application,when i try to run a few programs, i get the following error msg. wat do i do?"Compiler: Default compiler
Building Makefile: "C:\Dev-Cpp\workprojects\Makefile.win"
Executing make...
make.exe -f "C:\Dev-Cpp\workprojects\Makefile.win" all
gcc.exe -c project1/p2.c -o project1/p2.o -I"C:/Dev-Cpp/include"
gcc.exe: installation problem, cannot exec `cc1': No such file or directory
make.exe: *** [project1/p2.o] Error 1
Execution terminated"
also can u plz suggest some free c compilers which has a similiar interface like the compiler abv and works on vista?
P.S i cant figure out what the "installation problem" is, i tried reinstalling the application several times and i am getting more error messages if i try to include the directory containing gcc.exe in the compiler directories by clicking on tools

Unfortunately..... DevC++ will not work well with Windows Vista.

1. Dev C++ or aka Bloodshed is a 32 bit program.
elsewhere, Windows Vista is a 64 bit Operating System. It is not well compatible. It would have many errors for doing compilation.

2. For Free C Compiler, u may consider Microsoft Visual Express C++ (it can do C and C++) . It is Free, and It is the Express Edition, where u can download it at http://www.microsoft.com/express/vc or U may try google it for additional information.
It has a very nice interface, and it works well with Vista.
