jsc failing on windows

Probably upstream but just in case this has to do with the way jsvu is unpacking jsc:

An error message pops up:

I’m confused because jscLib.dll is definitely extracted:

Installing library to ~\.jsvu\engines\javascriptcore\jscLib.dll…

And it’s definitely there on disk and new. So it seems like maybe is somehow an invalid DLL?

The issue here is that certain third-party DLLs (e.g. ICU) are needed to run jsc.exe, so we’ll need to fetch and unzip a copy of WinCairoRequirements as well.

Sorry I missed this in #44—I had these DLLs in my path (and forgot that these are among the things that 32-bit AppleWin port references Program Files\iTunes for).

Putting WinCairoRequirements\bin64 on my PATH solved the crash on my end.
