Nuances of using Excel data sources with SSIS
Your Development Machine Setup
Needs Jet Drivers, available along with the default Office install so if you have Excel working fine locally, this is enough.
Installing the "Office Data Connectivity Components" (download file name AccessDatabaseEngine.exe) as well as having Office installed corrupts the Jet Driver stack so that SSIS in VS 2008 cannot create the object to read the XLS file. You will
see the title error "Unspecified Error" and "80004005" code.
Uninstall the Jet Engine pack on your development XP machine if you have Office. It will be listed as something like "Microsoft Access Database Engine (2010)".
Run Office 200x setup with the Repair option and reboot. Try configuring the task in SSIS and it should be able to read the Sheet names again and columns.
Live Server (32-bit and 64-bit)
Deploying your SSIS package to a server without Office 200x means it will not have the Jet Engine drivers to read XLS, XLSX files. You must install the 32-bit Office Data Connectivity Components - Jet Drivers mentioned above found here (http://www.microsoft.com/downloads/details.aspx?familyid=7554f536-8c28-4598-9b72-ef94e038c891&displaylang=en).
There are no 64-bit drivers; therefore regardless of 32 or 64-bit live environments, this step is the same.
