I have been using SkyDrive on Win 8/8.1 for about a year and a half. It works fine on my Surface and a spare Win 8.1 PC at work. On my primary work Win 8.1 PC it worked fine until July 21, 2014 when I started getting errors in the Application log. They all look like this.  I looked at all the threads listed when I posted this.  None of them has an answer I haven't tried.

I have not been able to get SkyDrive/OneDrive to run and sync since. The SkyDrive sync engine does not load and is not among running processes in Task Manager. I have scoured technet, answers, and any other Microsoft site for days to no avail.  I downloaded the ondrivets repair tool and ran it.  It tells me "OneDrive needs access to the folder "", which is unavailable.  I checked c:\users\"account name"\OneDrive to verify that my MS account had full control there.  It didn't so I added it.  My computer is connected to an AD domain. We switched domains in early July but SkyDrive worked for several weeks after the switch. I have disconnected and reconnected my MS account from Win 8.1 several times.  The SkyDrive sync engine just won't start.  I see many syncengine log files in the AppData \Local\Microsoft\Windows\SkyDrive\logs directory.  If there is a program that will read these perhaps I can figure out what is going on.

If I run the OneDrive app, it displays no files and there are no error messages.  The OneDrive item no longer appears in the left panel of File Explorer.  If OneDrive were a normal program, I would uninstall and reinstall it.  There doesn't seem to be any way to do that with OneDrive.

thanks, Mike

I finally got it working.  I had to disconnect my computer from active directory and reconnect.  After doing that with a restart in between, OneDrive started syncing properly.

I have the same problem. Running MS Diagnostics did not help. How did you disconnect your PC from Active Directory? Forgive my ignorance...
