Installer: WinPython-64bit-3.5.2.2Qt5
Operating System: Windows 10 Home

For some reason my Path variable did not have many common system paths.

If the System path variable does include some combination of %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\(source)
Then the WinPython Control Panel will not open any window at all, and will display no error message.
Opening the WinPython Interpreter will spawn a cmd.exe application with the error 'find' is not recognized as an internal or external command, operable program or batch file.

It would be a good idea to spawn a more informative error message when the proper DLLs(or programs) cannot be found for a proper sad path.

maybe should you check the size of the %PATH% variable:

  • in standard DOS mode,
  • when launching Winpython.

I'm not sure if the limit is 4091 or 2047

@stonebig My %PATH% variable length was always fine. Somehow It got truncated at some point however(unrelated). What is related is that WinPython doesn't respond or really even give an error when the %PATH% variable is incorrectly set.
