It is harder with julia-0.3.0-prerelease. I tried the win64 version in Windows 7. (Other Windows versions should be similar, but I cannot test them.)
We still need a batch file. I named it Julia.bat. It contains (with my test setup path) only 2 lines ~~~~~ @"c:\t\Julia 0.3.0-prerelease\bin\julia-readline.exe" %* if errorlevel 1 pause ~~~~~ Then we need to open a command prompt window with administrator privileges (important!), and type in (again with my test path) ~~~~~ ftype julia=c:\t\Julia 0.3.0-prerelease\julia.bat %0 assoc .jl=julia ~~~~~ (In some Windows versions you may need to reboot or kill Explorer, which immediately restarts taking the new settings - but Win7 works right away.) Just change the path in both places to fit your setup. Double clicking on (or executing) a *.jl file will run it via the batch file. At an error the opened console window will not close, but waits for a key press, so we can read the error messages. (I edit Julia files in Notepad++, and with F9 to execute the current file, it is just a keystroke to run a program.)
