error opening Workspace

I recently upgraded a server w/ Engine installed to 10.1 sp1 from 10.0.  I have some code in a simple console app that creates XY events from a spreadsheet and then writes those features into a SDE instance.  Since the upgrade, the code bombs when I try to open a workspace from the spreadsheet - code below.  Any ideas what I'm missing or may have changed from 10.0?

Thanks, TG

            Console.WriteLine("Import Starting - " + DateTime.Now.ToShortTimeString());
                //Open XLS as table & make XY layer
                factoryType = Type.GetTypeFromProgID("esriDataSourcesOleDB.ExcelWorkspaceFactory");

                WSFac = (IWorkspaceFactory)Activator.CreateInstance(factoryType);
                Console.WriteLine("Looking for " + strXLSarchive);
                Console.WriteLine("does file exists " + File.Exists(strXLSarchive).ToString());

                WS = WSFac.OpenFromFile(strXLSarchive, 0);   <--  falls into the Catch block here
                Console.WriteLine("WS opened");

                fWS = (IFeatureWorkspace)WS;
                table = fWS.OpenTable(strXLSsheet);
                ds = table as IDataset;

                XYProps = new XYEvent2FieldsPropertiesClass()
                    XFieldName = strXField,
                    YFieldName = strYField

                XYName = new XYEventSourceNameClass()
                    EventProperties = XYProps,
                    SpatialReference = srWGS84,
                    EventTableName = ds.FullName

                XYEvent = (XYName as IName).Open() as IXYEventSource;
                fcInput = XYEvent as IFeatureClass;

            catch (Exception ex)
                strMsg = "0;Failed to create XYEvents from XLS: " + ex.Message + ";" + ex.GetType().ToString();
                WriteLog(strMsg, true);

strMsg that's echoed and logged is -
0;Failed to create XYEvents from XLS: Exception from HRESULT: 0x80040213;System.Runtime.InteropServices.COMException;2/12/2013;1:41:13 PM

my debugging WriteLine statements echo the correct file name and that it does exist.

Code runs fine on my PC debugging in VS2010
