MoveFile failed; code 183.
Cannot create a file when that file already exists.
Solution:
Executable files are likely stuck open somewhere, either on the FOS Server or a User's machine.
1. Click the "Abort" button.
2. On the server, select Administrative Tools --> Server Manager --> Roles --> File Services -->Share and Storage (right click) --> select Manage Open files
3. Select the C:\FOS files and close selected. You will get a pop up – as long as no users are connected click OK. If this does not work, you can also reboot the FOS server to clear any open files / connections.
4. After closing the open files / connections, re-perform the steps for the FOS Update.
***Another option, rather than performing Steps 2-4, is to reboot the FOS server.
