I'm using Windows 7 x64. OneDrive is not syncing. I drag files to the OneDrive folder (it shows up in FileExplorer with a blue cloud icon) but the files do not show up in the web UI when I open it on a different computer.
I no longer have a OneDrive icon in the system tray, so this troubleshooting page doesn't help since it bases the help on the color of the icon in the system tray.
I wonder if by installing Office 2016 a while ago, my previous OneDrive install got clobbered.
How would I reinstall the OneDrive desktop app for Windows 7 x64 without losing everything that has been copied up to the cloud?
