System.InvalidCastException: Unable to cast COM object of type 'System._ComObject' to interface type '.Workbook'. MSI file for the users with the below issues but this didn’t help.

Most users can install the application using CLICK ONCE and are fine.

This error does not appear for all users. When the application calls Excel to EXPORT a workbook the workbook appears unpopulated and the below detailed error message is displayed. I have a VB.net windows application developed using VS2008 running on a Windows 7 machine calling EXCEL 2003.
