Receiving error during update: 'The process cannot access the file 'C:\Program Files (x86)\DBA Manufacturing\Castle.Core.dll' because it is being used by another process.'


The following error can be received when you try to update DBA: 'The process cannot access the file 'C:\Program Files (x86)\DBA Manufacturing\Castle.Core.dll' because it is being used by another process.'  This error message is saying that the update cannot run because the Backup Manager App is open, which is accessing the Castle.Core.dll file.  

To clear this error message, you should close the Backup Manager App by clicking the red X in the Backup Manager window.  Once you have closed the Backup Manager, you should be able to update without hitting this error.
