I have a system running on 15 different XP systems and 1 Vista box. The application calls Excel 2000 with:

oExcel = GetObject(, "Excel.Application")

Things have run fine for several years. The client got a new Vista box and now when I run the above line in the Command Window I get

OLE error code 0x800401e3: Operation unavailable

Any idea what the problem may be?
