I'm trying to install the latest preview build (10586.71) on my 950XL and it isn't succeeding. It downloads completely, gets into "preparing to install," then gives me the "Some update files are missing or have problems. We'll try to download the update again later. Error code: (0x80073712)"
... I tried a few times yesterday, then again today. I've done a soft reset, removed the battery for a harder reset, tried under a couple of different Wi-Fi connections. I have plenty of free space for the update. I suppose Clippy will suggest doing the things I just listed, then a factory reset, but does anyone have any other ideas on how to get around this? It's not a new error but I haven't found a lot of useful discussion in the forum about what the error actually means and how to resolve it on a phone, though it does appear that on desktop versions of Windows this error can be resolved by using some sort of recovery tool, rather than reformatting one's hard drive. Here's hoping.
