I have attempted to upgrade Windows 8 Pro (Msdn) to 8.1. The install gets as far as 'Applying changes, then comes up wiith the extremely helpful error message 'The application wasn't installed'. Clicking on view details gives, the equally helpful, 'Something happened and Windows 8.1 couldn't be installed> Please try again. Error Code: 0x80070057.
What is going on here?
On a second note, I have two PCs running Windows 8. One of them had the upgrade on offer this morning, the other didn't. Curiouser and curiouser.
