Excel add-ins do not cause memory problems. We have had all of our add-ins (80+) loaded at one time and working fine without any memory issues. Excel add-ins are designed to work within Excel and Excel manages all memory.
We have even seen a case where Excel's own calculation functions return errors and formulas in Excel return errors.Īll of our add-ins are Excel add-ins and are not COM add-ins. They can cause regular add-ins not to work correctly, as Excel runs out of memory. Excel frequently runs into memory problems if COM add-ins are installed. They are created outside of Excel by special programs and designed to work within Excel.
