I am attempting to install Flow into a fresh 3.7b image.
Currently I am on Windows XP.

The initial attempt fails due to no PackageInfo being installed.
I install PackageInfo and then I run into this DNU.

UndefinedObject(Object)>>doesNotUnderstand: #binary
ZipFileMember(ZipArchiveMember)>>extractTo:

I don't understand where the problem is or how to resolve this.
I browsed the ZipFile/ArchiveMember and don't know why there is a problem.

Any help greatly appreciated.
