Closing this as invalid as it is an HP issue, which in general should be reported here: https://github.com/haskell/haskell-platform
That said, these two directories are not places that the platform installer itself creates or installs things to. They are, however, the
#11696: Windows Install Makes Unnecessary/Incorrect PATH Changes -------------------------------------+------------------------------------- Reporter: AlexAndrews | Owner: Type: bug | Status: closed Priority: normal | Milestone: Component: None | Version: 7.10.3 Resolution: invalid | Keywords: path | environment variable install Operating System: Windows | Architecture: x86 Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by AlexAndrews): Replying to [comment:2 gershomb]: directories that cabal will create and install things to by default when you `cabal install` an executable , and thus the platform installer (correctly) adds them to your path as a convenience. We can document this behavior further, but I see no need to change it. Fair enough, but having asked where Haskell should be installed, the HP should also ask where to locate the directories that `cabal install` will use. I will submit an HP ticket on the URL you provided. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11696#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
