c++ - Windows - only the first entry of PATH-environment variable can be found -

The following problem is with my PATH-environment variable for some time, and it has become unbearable, so I can help you I will appreciate a lot.

The following is the content of my system environment variable, which gives output to% PATH% on CMD-XE.

C: \ minjiw \ bin; C: \ Program Files (x86) \ Microsoft Visual Studio 12.0 \ VC \ bin; C: \ msys \ 1.0 \ bin; C: \ QT \ 5.3 \ msvc2013_64 \ bin; C: \ Users \ Public \ Documents \ Embarcadero \ Studio \ 15.0 \ Bpl; C: \ Program Files (x86) \ Embarcadero \ Studio \ 15.0 \ bin64; C: \ Users \ Public \ Documents \ Embarcadero \ Studio \ 15.0 \ Bpl \ Win64; C: \ Program Files \ Doxygen \ bin;% ANT_HOME% \ bin; % JAVA_HOME% \ bin; % M2_HOME% \ bin; C: \ Program Files (x86) \ MiKTeX 2.8 \ miktex \ bin; C: \ Program Files \ PDF Split and Merge Basic \ Bin; C: \ Program Files \ Microsoft \ Web Platform Installer; C: \ Program Files (x86) \ Microsoft asp.NET \ asp.net Web Page \ v1.0 \: C: \ Program Files \ Microsoft SQL Server \ 110 \ Tools \ Bin; C: \ Program Files (x86) \ Windows Live \ shared;% SystemRoot% \ system32;% SystemRoot%;% SystemRoot% \ System32 \ Wbem;% SYSTEMROOT% \ System32 \ WindowsPowerShell \ v1.0 \; C: \ Program Files (x86) \ ATI Technologies \ ATI CE \ Core-Static; C: \ Program Files \ Slix \ Bin; C: \ Program Files (x86) \ Windows Kit \ 8.1. Windows Display Toolkit; C: \ Program Files (x86) \ Microsoft SDK \ TypeScript \ 1.0; C: \ Program Files \ Microsoft SQL Server \ 120 \ Tools \ Binny \: C: \ Program Files \ Doxision \ Bin

It is now, that only its first entry can be used, that is The command can be found in "G ++" (which is in C: \ mingid bin), but already "CL" (which is in C: \ Program Files (x86) \ Microsoft Visual Studio 12.0 \ VC \ bin)

What am I doing?
