What to do if using Microsoft Vista and Exl-Plans help files fail to load and Excel indicates “There was a problem running the macro (1037).”?
The initial release of Vista excluded the very widely-used Help program (WinHlp32.exe) for use with the HLP format help files used by some versions of Exl-Plan. To access these help files, you must download and install the WinHlp32.exe program from the Microsoft Download Center. If this link is broken, search the Microsoft site for “Windows Help program (WinHlp32.exe) for Windows Vista”. For more information about WinHlp32.exe, see this Microsoft article.
