“Our shipment scheduler crashed for three users. Error says: ‘Component ‘MSCAL.OCX’ not registered or file missing.’ We’re on Windows 11 now.” Priya got a panicked call on a Tuesday morning
“Leo, remember the old VB6 app that draws the dispatch calendar? It’s asking for MSCAL.OCX 7.0.” mscal.ocx version 7.0
