HomeTroubleshooting@RISK for Excel: SimulationMissing Results Graph

4.16. Missing Results Graph

Applies to: @RISK 7.5.1, possibly some earlier releases also

After a simulation, I don't get a results graph. Instead, the graph area is full of a gray rectangle, with a white rectangle in the upper left.

Or:

The results graph appears, but I can't move the delimiters or change the percentages at the top.

Or:

The results graph appears, but there's no statistics grid and the drop-down arrow to let me select the grid does not appear at the upper right of the window.

Or:

The Define Distributions window freezes when I select a distribution.

These symptoms all have the same underlying cause: @RISK is trying to access a .NET 2 file that does not exist but is still registered. The cure is to re-register your .NET  4, by following these steps:

  1. Close all open copies of Excel.

  2. Open an administrative command prompt—here are directions in case you need them.

  3. You'll need to copy/paste two commands to the administrative command prompt, one command at a time. To copy a command, highlight the entire command with your mouse and press Ctrl+C. To paste the command, right-click into the administrative command prompt, select Paste with the mouse, and press the Enter key on your keyboard.

    • If you have 64-bit Windows, with either 32-bit Excel or 64-bit Excel, copy/paste this command:
      C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe "c:\Program Files (x86)\Palisade\System\Palisade.DecisionTools.Graphing7.dll" /u

      Then copy/paste this command:
      C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe "c:\Program Files (x86)\Palisade\System\Palisade.DecisionTools.Graphing7.dll" /codebase /tlb

    • If you have 32-bit Windows, copy/paste this command:
      C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe "c:\Program Files\Palisade\System\Palisade.DecisionTools.Graphing7.dll" /u

      Then copy/paste this command:
      C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe "c:\Program Files\Palisade\System\Palisade.DecisionTools.Graphing7.dll" /codebase /tlb

  4. The command prompt window will show some output, which should include "Types registered successfully" and "type library was registered successfully". Take a screen shot of the output, to be sent to us if you don't see those messages in the output, or if the fix doesn't work.

  5. Run @RISK, and you should see that the original problem has been resolved.

  6. If @RISK still does not run correctly, verify that .NET Framework 4 is enabled.

    • In Windows XP through Windows 7, Control Panel » Programs and Features and verify that .NET 4 is in the list of installed programs.
    • In Windows 8, 8.1, and 10, Control Panel » Programs and Features » Turn Windows Features On or Off and verify that .NET 4 has a check mark.
  7. If @RISK still does not run correctly, run the Microsoft .NET Framework Repair Tool.
