Yet Another MinGW "gcc: error: CreateProcess: No such file or directory"
You shouldn't add C:\MinGw\libexec\gcc\mingw32\4.7.2 to the path.
Add: c:\MinGW\bin
You may need to reboot to ensure that the path is made available to all processes properly.
Another suggestion is to use a different MinGW distribution. It's been a long time since I used an 'official' MinGW distribution because the installation steps were so byzantine and fragile. I've heard they've made large advances to the installer, but from what I hear it still seems to be rather complicated and fragile.
TDM's installer just works, but I think the TDM release isn't quite to 4.7.2.
The nuwen distribution's installation is just unpacking an archive where you want the thing (I love that!) and making sure the path points to the location of gcc.exe. Nuwen also packages the boost libraries, which is nice.
I case it helps, here's what I get from gcc -v hello.c (c:\mingw.4.7.2\bin is in the path`):

I had the same error. I have 64 bit win 7 OS. First I installed 32 bit MinGW, gcc was installed successfully but showing this error. Tried installing 64 bit MinGW but failed to install. Searched a lot, tried many things but nothing worked.
Finally installed "tdm64-gcc-5.1.0-2" from this link >> https://sourceforge.net/projects/tdm-gcc/?source=typ_redirect
It installed & worked in single attempt without any error. Nothing special tried.
And the basic important point, after installation need to add "bin" directory on env path ('C:\TDM-GCC-64\bin' in my case). Then check gcc installation from this command on console >> "gcc --version" , this will show the gcc version installed.
