I have followed all the steps as it is..DelayValidation is set to true..Run64bit is set to false..when I preview the data in Excel source..SSIS is showing the data properly..but when I try to run the package I am still getting this error:

The AcquireConnection method call to the connection manager "Excel Connection Manager" failed with error code 0xC0202009. 

Can somebody please help in resolving this issue? Thanks in advance..
