IDLE not working in ActivePython

The problem is that "idle.bat" is missing some double-quotes. If you have installed Python in "C:\Programs files\Python27" instead of "C:\Python27\", "idle.bat" will fail to execute "idle.pyw".

Copy and paste the follow 2 lines in "C:\Program Files\Python27\Lib\idlelib\idle.bat" (or wherever "idle.bat" is located) to fix it:


@echo off
rem Start IDLE using the appropriate Python interpreter
set CURRDIR=%~dp0
start "%CURRDIR%..\..\pythonw.exe" "%CURRDIR%idle.pyw" %1 %2 %3 %4 %5 %6 %7 %8 %9
