Why the windows download needs an "alternative"

[connor4312]

        // This alternative strategy shouldn't be necessary but sometimes on Windows the file does not get closed,
        // so unzipping it fails, and I don't know why.

I think this is because the promise resolves on('finish' of the outFile. This is when contents have been written, but the file is not yet closed. Changing that to on('close' should resolve the issue.
