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

[58 of 58] Compiling Main             ( Setup.hs, Setup.o )

Linking Setup.exe ...

>Setup configure

Configuring Cabal-1.8.0.4...

>Setup build

Preprocessing library Cabal-1.8.0.4...

Building Cabal-1.8.0.4...

Registering Cabal-1.8.0.4...

>Setup install

Setup: permission denied

>

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.
