Problem: Gcc compiler / Scilab 5.3.1 version - 64 bits / MinGW / Scilab demonstrations

[Prof. Dr. Reinaldo Golmia Dante]

Hi Scilab users,
 
I uninstalled my Scilab 5.3 version 32 bits for Win 7 Home Edition to exchange to Scilab 5.3.1 version 64 bits, and
I simply deleted the gcc 32bits folder to install gcc 64bits through gcc-4.5.2-64.exe.
 
I executed gcc-4.5.2-64.exe and loggoff and login again my notebook.
 
Then, I tried to install MinGW typing:
 
<<
-->atomsInstall('mingw')
 ans  =
 
!mingw  0.8-1  user  SCIHOME\atoms\mingw\0.8-1  I  !
 
>>
 

I restarted Scilab again and appeared the message:

<<
Startup execution:
  loading initial environment
 
Mingw Compiler support for Scilab
 Load macros
 Load help

 >>
 
It seems that works well until I try to run a Scilab demonstration: I select "RCL circuit" and
click "START".
The Scilab console appears the message:

I think that gcc does not run properly. When I installed it, appeared a message that gcc was installed successfully !
When I used Scilab 5.3.0 and gcc-4.5.1-32.exe, all Scilab demonstrations worked very well .. 
But now with Scilab 5.3.1 version - 64 bits and gcc-4.5.2-64.exe ... they don't ...
 
Isn't it enough to run gcc-4.5.2-64.exe to install gcc compiler in my Windows 7 Home edition 64 bits ? How can I set up my Windows to
recognize gcc compiler ? And if there is a file like "makefile", how can I find it in Win 7 ?
 
Thank you in advance.
 
All best,
Reinaldo.
