SSIS Excel Connection Manager Error : SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER

SSIS Excel Connection Manager Error : SSIS Error Code DTS_E_OLEDBERROR

Error Message :

I am trying to write my first BI package in VS 2005 to do a simple excel to SQL Server 2005 load. I have a simple dataflow containing an excel source and sql server destination. The Excel source is connected to an Excel 2003 worksheet. My machine is vista -64bit.

While debugging I get the following errors which do not help me much...can anyone tell me what I am doing wrong?

1). After "Progress Validating"

[Excel Source [1]] Error: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. 

The AcquireConnection method call to the connection manager "Excel Connection Manager" failed with error code 0xC0202009. There may be error messages posted before this with more information on why the AcquireConnection method call failed.

2). After "Validation is Complete"

Solution :

This issue is occuring because you are having a 64 bit OS and Office Excel (including most of the office products) does not have 64bit provider and hence the error above on Excel connection.
You can solve this issue by setting Run64BitRunTime property as False.
