Check compatibility between MathCAD 15 and Excel versions.

MathCAD 15 is VERY old and no longer supported by PTC.

The error you're experiencing suggests that there might be compatibility issues between Mathcad 15 and Microsoft Excel 2013. The Windows Debugger (WinDbg) output indicates the issue might be with the Windows on Windows (WoW64) subsystem, which is the part of the Windows OS that allows running 32-bit applications on a 64-bit system.

Mathcad 15 is a bit older software and it was designed to work best with the software versions available at the time of its release. Mathcad 15 is officially compatible with Microsoft Excel up to the 2010 version.

Here are a few suggestions to troubleshoot this issue:

1. Run in Compatibility Mode: You can try running Mathcad 15 in compatibility mode. Right-click the Mathcad 15 shortcut or the Mathcad15.exe file, choose Properties, go to the Compatibility tab, and select the mode that corresponds to an older version of Windows (like Windows 7 or 8).
2. Check Excel Version: If possible, try downgrading your Excel to a version that's officially supported by Mathcad 15, such as Excel 2010.
