Multiple installations of ghc-mod

Question

I have noticed I have 3 sets of ghc-mod.exe, ghc-modi.exe etc on my computer. The first one I suspect was created with stack. It is in

c:\\users\\myname\\appdata\\roaming\\local\\bin

The 2nd one I think was created with cabal and is in

c:\\users\\myname\\appdata\\roaming\\cabal\\bin

and the 3rd one again I suspect was created with stack. It is in

C:\\stack_root\\snapshots\\48375d44\\bin

. At the moment my PATH is pointing to all 3 however I have renamed ghc-modi.exe and ghc-mod.exe in 2 folders and left version 5.6.0.0 in ~\\roaming\\cabal\\bin unchanged. The whole thing is somewhat confusing and I suspect unnecessary. Do I need all 3 versions? How can I clean it up?
