[Haskell-cafe] unable to load package `regex-posix-0.94.2' (On Vista x64)

[__kaveh__]

I am using Vista x64. I have Haskell platform installed (Latest
varsion -available for Windows, 2010.2.0.0, GHC 6.12.3).
When I am trying to run picnic.hs from "How To Organize a Picnic on a
Computer" tutorial. I get this:

C:\...>runhaskell picnic.hs

picnic.hs:46:18:

([0-9.]+)") s

I have tried to update using (cmd is running as administrator):

C:\Windows\system32>cabal update
Downloading the latest package list from hackage.haskell.org

And then installing package using cabal:

C:\Windows\system32>cabal install regex-posix [--reinstall] --global

And why the cabal package installs at "C:\Program Files
(x86)\Haskell"? Shouldn't it be "C:\Program Files (x86)\Haskell
Platform\2010.2.0.0"?

Thanks
