I've had this issue before, but I don't remember how it was solved. The recent patch causes "Update Failure. Error Code -1"

Someone move this to the "Bugs" forum

What does the rest of the Updater log say? And what platform/OS are you using?

Sorry, I put this in General because I was sure it was not a bug, but an issue on my end. VO updated just fine on the latest attempt.

Thanks for the update.
