Vita's PC Content Manager updates, doesn't work

Well, this is the most boring post I'll ever write. There's an update for the PS Vita's Windows Content Manager, plug your Vita into the PC and it'll try and install. But it never completes, going into a close, restart, reinstall loop.

Who knows if it does anything new, hopefully it will speed things up when transferring data, which is about the only thing it is designed for, yet does it horribly slowly. To be honest, I'm happier deleting and reinstalling games as I need them rather than mucking about with this piece of crap. Anyone got it working and seen an improvement?
