Solved. I created another user account.. The 1327 error means one of the library destinations (Document, Pictures) is not working well with installation. I had just changed every one of them to point to network shares rather than be on local PC Rather than update them in the registry, I created another administrator account without all the relocations and it installed. Had to run it as administrator to get Live update to work and it took 20 minutes to download changes but all working now.
