Possible Causes and Solutions

Restart Windows – close all programs and perform a full system restart, not just log off/on.
Test multiple models – see if the error occurs in more than one file.
Check Excel add-ins – disable active add-ins and re-enable them one by one to identify conflicts. See Find and Fix Startup Conflicts (Excel 2007–2016).
Multiple CPU setting – for small simulations, set Multiple CPU to Disabled in Simulation Settings on the General tab.
Multiple Excel versions – some customers with multiple Excel versions saw the error in Excel 2013 but not 2010 or 2007.
Outdated COM references – remove references to Excel or Project versions not installed on your system. See Removing Outdated References to Office from the System Registry.
@RISK for Project 4.1.4 – background Excel processes may block @RISK. Use Task Manager to close all Excel.exe processes, then restart Project and @RISK.
