Error to launch winghci shipped in haskell platform package 2012.2.0.0

Question

Everytime I double click winghci.exe an error message CreateGHCiProcess failed with failed with error 2 pops. I assume the installation hasn't completed setting environment variables successfully since cmd C:\>ghci ends up with no command found either. Could anyone help posting changes that might take place during the installation or any solution to this?

Answer 1

To complete the incomplete answer: add the path of the bin directory inside your haskell platform folder, e.g. C:\Programs\Haskell Platform\2012.2.0.0\bin, to your PATH. That should be all.

Answer 2

Issue closed. Solution is to set $PATH$ by either reinstallation or manual

Answer 3

I think that's supposed to be %PATH% when you're dealing with windows.

path = c:\programs\Haskell Platform\2012.2.0.0\bin;%path% for your example.

You could also make a shortcut and point the "Start in:" entry at where you've installed the bin directory.

For me, I have it installed under "c:\users[ME]\my documents\dev\Haskell Playform\2013.2.0.0\bin"

Starts up fine.
