Some advanced versions use mscomctl.ocx or Microsoft Scripting Runtime. If you get a "Can't load object" error:

  • Click OK.

    • An ogee spillway is a commonly used overflow crest shape for dams and spillways, designed to match the lower nappe profile of a prismatic structure under free-flowing conditions. Its curved profile minimizes flow separation and energy losses, providing efficient discharge and predictable hydraulic performance for overtopping flows.

    Even with a clean ogee spillway designxls install, issues occur. Here are fixes for the top 5 problems.

    | Error Message | Likely Cause | Solution | |---------------|--------------|----------| | "Cannot run the macro... macros may be disabled" | Excel security settings | Re-enable macros per Part 2. | | "Compile error: Can't find project or library" | Missing VBA reference | Open VBA editor > Tools > References > uncheck "MISSING" items. | | "Solver: Not an available reference" | Solver add-in not loaded | Reinstall Solver via Excel Add-ins (Part 3, Step 5). | | "Run-time error 1004: Application-defined error" | Data validation conflict | Clear all input cells, then re-enter values as numbers (not text). | | "File is corrupt and cannot be opened" | Downloaded incorrectly or OneDrive conflict | Re-download the zip, extract to local drive C: only. | Some advanced versions use mscomctl

    The discharge coefficient (C) is often derived from a lookup table. The user must verify that the table ranges match the input units. For example, if the spreadsheet expects H_d in meters but the user inputs feet, the coefficient will be incorrect. No software installation fixes this—it requires manual unit verification.

    To avoid a failed ogee spillway designxls install, verify your system meets these prerequisites. Click OK

    | Component | Requirement | |-----------|--------------| | OS | Windows 10, 11 (64-bit) or macOS with Parallels/VMware | | Excel Version | Microsoft Excel 2016 or later (Office 365 recommended) | | Memory | 4 GB RAM minimum | | Add-ins | Solver Add-in and Analysis ToolPak must be enabled | | Macros | Must allow signed macros (for .xlsm versions) |

    The purpose of this report is to document the successful installation, configuration, and preliminary validation of the Ogee spillway design spreadsheet tool. This tool is intended to support preliminary hydraulic design of overflow spillways according to the USBR (United States Bureau of Reclamation) or USACE (United States Army Corps of Engineers) methodology.

    Many Ogee spreadsheets use Solver to optimize the crest curve transition.
