Applies to: @RISK 7.5.1 and lower

Symptoms:

• The results graph displays a gray rectangle with a white rectangle in the upper left?
• Can't move the delimiters/change percentages/access the statistics grid and dropdown arrow
• The Define Distributions window freezes when selecting a distribution
• The delimiters divide the graph into three regions based on percentages that are shown above the graph?

Cause:

@RISK is trying to access a .NET 2 file that does not exist but is still registered.

Solution:

Re-register .NET  4:

1. Close all open copies of Excel.

2. Open an administrative command prompt

3. Copy/paste two commands to the administrative command prompt, one command at a time.

   • 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".

   1. 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

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

7. If @RISK still does not run correctly, run the Microsoft .NET Framework Repair Tool.
