A fresh install on windows 10 enterprise using:

HaskellPlatform-8.6.3-core-x86_64-setup.exe

run as administrator crashes every time I try to start with this error (from powershell):

Trying to run ghci and winghci also crashes, but no error.

This is a company computer and I don't have admin rights, so I can't try and reinstall very easily.

I seem to recall the installation trying to put something in the admin's local directory but we changed this to my local directory. I googled around and only found similar things with compiling. For fun I tried:

PS C:\Users\rburgess> ghci -fexternal-interpreter
GHCi, version 8.6.3: http://www.haskell.org/ghc/  :? for help
ghc-iserv: internal error: IMAGE_REL_AMD64_ADDR32[NB]: High bits are set in 24d38172659 for ghczmprim_GHCziTypes_ZMZN_closure

    Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

Any help appreciated. It was hard enough to get this approved, I don't want to get some admin back unless a resolution is very likely. I use this as an argument to get them to let me run linux on my computer where I've never had a problem with ghci. :) But if I'm going to sell them on haskell, it would be nice to get it working locally. Let me know if you need other info or try non-admin things. Thanks! --rob
