Does someone have the spreadsheet open? Try it with an old spreadsheet to see if anything has changed.
========================================== Cursors are useful if you don't know sql. SSIS can be used in a similar way. Beer is not cold and it isn't fizzy.
I get this error even when I create a new SSIS package and drag the toolbox object. The spreadsheet is closed. None of the SSIS packages are working. they all are giving the same error. I think there is something wrong at the configuration level, install files or dlls.
