Unable to Install old-time-1.1.0.3 on Windows under Haskell Platform

[iamrecursion]

I've been trying to install some modules that depend (indirectly, in most cases) on old-time on windows today, and the install fails. It can be reproduced by attempting a cabal install old-time in by itself, but does not occur in a cabal sandbox. The crux of the issue seems to arise form missing interfaces in old-locale as follows:

Preprocessing library old-time-1.1.0.3...
[1 of 1] Compiling System.Time      ( dist\build\System\Time.hs, dist\build\System\Time.o )

System\Time.hsc:117:1: error:
    Failed to load interface for `System.Locale'
    There are files missing in the `old-locale-1.0.0.7' package,
    try running 'ghc-pkg check'.
    Use -v to see a list of the files searched for.

This is occurring on a fresh install of Haskell Platform. It looks like the version of old-locale bundled with the platform is the same version number (1.0.0.7) as is downloaded into a sandbox, but not the same contents. Indeed, forcing a ghc-pkg unregister old-locale --force, cabal install old-locale before trying cabal install old-time again fixes the issue.

Let me know if there is any additional information I can provide that will be helpful. I'm not really sure what you can do yourself to fix this, but I figured I'd report it anyway.

The platform hasn't shipped old-locale since 7.10.3? Is this a prior version of the platform then?

[iamrecursion]

Much more recent... perhaps I ended up with a corrupt install somehow.

[gbaz]

which version precisely -- 32 or 64 bit, which ghc, minimal or core?

it may be an issue with one installer in particular...

[iamrecursion]

It was the 64-bit re-release of 8.0.2 due to the Windows 10 Creators update issue. Full installer.

I've since moved away from it to use slack for managing my GHC installs.
