I received the following errors in the Microsoft ODBC Data Source manager (64-bit), for my data source an MS Access DB (.accdb), after updating to Windows 10 from 7 and uninstalling MS 2010 and installing 2013:
"The driver of this User DSN does not exist. It can only be removed."
And also: "The driver of this 64-bit System DSN does not exist. It can only be removed."
There doesn't seem to be any results when searching for the error for this online (other than one result with DLL info).
