C:\Users\Ralph> From: haskell-cafe-bounces@haskell.org [mailto:haskell-cafe-bounces@haskell.org] On Behalf Of Ralph Hodgson Sent: Monday, May 17, 2010 12:18 AM To: haskell-cafe@haskell.org Subject: [Haskell-cafe] Windows 7 Permission Denied Problem on Cabal Following a successful install of the Haskell Platform on MAC OSX, I proceed to update my Windows PC. Frustration followed. I am blocked by a "Permission Denied" error when I do a "Setup install":
ghc --make Setup

I changed the permission on folders in the "Haskell Platform" directories to "full control", without any effect. I have searched the web for help but could not find my problem. Can't help but think it is something trivial but what? Help appreciated. Ralph Hodgson, @ralphtq http://twitter.com/ralphtq
