Excel XLSX format as a source

Using the following:

Microsoft SQL Server Standard (64-bit) version 11.0.5058.0

Microsoft Visual Basic 2010 Shell

Microsoft SQL Server Integration Services Designer Version 11.0.5058.0

I am simply trying to import data from a sheet in an excel workbook (XLSX) into an existing SS table.

I set up an excel source and created an Excel Connection manager, and the connection string is this:

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\\vmwd-stsqldb02\c$\temp\NewAccounts.XLSX;Extended Properties="EXCEL 12.0 XML;HDR=YES";

In the Excel Source Editor it will not pull up and of the sheets, it states 'No tables or views could be loaded.'.

I have gone to http://www.microsoft.com/en-us/download/details.aspx?id=13255 as some posts have suggested and installed the 64-bit driver.  This did not work.

I am open to any suggestions.

Thanks !
