I'm running Windows 8.1 Pro. I've had Google File Stream stop three times now. The first time I was completely puzzled, so I reinstalled it. The second time I used Windows search to find the app and started it manually. I can't recall any precursor events for those instances.
Today, after I re-started Windows to finish an update, Google File Stream was not running. I searched for it and it does not show up. I tried reinstalling it, and the installer objected that I had a newer version installed. I found it in Control Panel:Programs and Features. See the attached image. Note the little bit of a folder at the bottom right that shows the status of my google drive as "not syncing".
I'm going to uninstall and re-install, but I would like to fix this problem. Does anyone have any thoughts?
