It would seem a few clients are encountering issues with this specific application, as it doesn't start on various machines running the 8.1 Preview.

"I am running Windows 8.1 completely overhauled. When i start the Skydrive application from the begin screen it acts like it is set to begin the close down and I am once again to the Start screen once more," one client clarified.

Microsoft asserts that this is a known bug, so anticipate that new fixes will address the issue in the nearing weeks. Obviously, all these issues should be fixed soon after the last form of the OS upgrade turns out in August.
