no excel is not open,and the path also correct.
i run the following code
EXEC sp_MSset_oledb_prop N'Microsoft.ACE.OLEDB.12.0', N'AllowInProcess', 1
GO
EXEC sp_MSset_oledb_prop N'Microsoft.ACE.OLEDB.12.0', N'DynamicParameters', 1
GO
After that it shows
Msg 7308, Level 16, State 1, Line 1
OLE DB provider 'Microsoft.ACE.OLEDB.12.0' cannot be used for distributed queries because the provider is configured to run in single-threaded apartment mode.
