I am trying to set up TCC on Windows 7, but I can't seem to make it work dynamically from cmd

To be able to invoke the compiler from everywhere on your computer by
just typing "tcc", please add the directory containing tcc.exe to your
system PATH.

So I changed my environment variable that said "Path" from:

C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\

To:

C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\; C:\compilers\tcc\tcc.exe

But when I open cmd, it still says that "tcc" is not a recognized command.

    Do you think C:\compilers\tcc\tcc.exe is a valid folder name? Read path

You have added the location to the .exe file named tcc.exe in your path. What you should do is add the location of the folder containing the tcc.exe file. So in your case the environmental path variable should be like this

C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\; C:\compilers\tcc

Assuming that your tcc.exe file is in the folder is C:\compilters\tcc

Path command (see windows command line reference):

Sets the command path in the PATH environment variable, which is the set of directories used to search for executable files. Used without parameters, path displays the current command path.

Your C:\compilers\tcc\tcc.exe is not a valid folder (directory) name; supposedly, should be rather C:\compilers\tcc\ or C:\compilers\tcc (with or without trailing \ backslash).
