Also, even though we are in 2013, I still personally avoid spaces in paths for programs in windows that I'm going to use from the shell.

I reinstallesd haskell platform without spaces. Something changed!
A first attempt to cabal.exe update resulted in a segmentation fault, the second worked. Now if I do:

cabal install netwire

I cet:

$ cabal install netwire
cabal.exe:

nothing else ...
