Attempting to run SmartConnect maps using Excel as a datasource.  Maps have been working fine until recently when all my Excel maps starting giving the error that says, “Error [HY000] [Microsoft] [ODBC Excel Driver] Reserved error (-5016); there is no message for this error.”  Double clicking on the error results in additional information that looks like this.



How to resolve this error?

---

This error is caused by a recent set of Windows updates that breaks ODBC connectivity for Excel.  We are hoping that Microsoft releases a fix for this soon, however until that time the only solution is to uninstall specific Windows updates depending on the operating system.  Following is a list of the updates that need to be uninstalled.  After uninstalling the updates, you will need to reboot the machine.  After the reboot the maps will function correctly again.
