How to configure cabal in Windows 7?

Question

I have installed Haskell Platform 2012 in Windows 7. I write in the console cabal update and I take a message that there is a new version of cabal. I write cabal install cabal-install . After installation finishes it tells me that the cabal has been installed in C:\username\AppData\Roaming\cabal. So when I do cabal update again I am taking the same message that I have to install the new version of cabal. I have tried to change the cabal directory from the config file but cabal ignores the config file. Is Haskell working only on Unix? Thanks

The problem is that the cabal executable that came with Haskell Platform gets picked up instead of the one that you installed.

You need to edit the value of the PATH environment variable and place %AppData%\cabal\bin before %PROGRAMFILES%\Haskell Platform\...\bin so that it's given higher priority.
