Clarity PPM On Premise


  • Symptoms reported include:
    • The CA Clarity PPM Integration Addin keeps getting disabled, and it has to be re-enabled each time Microsoft Project (MSP) is opened.
    • 'caclarityaddin' gets unloaded / ribbon is gone every time MSP is launched/Integration tag not available
  • This prevents the MSP Interface/schedule connector from working properly with Clarity until it's reenabled
  • To Verify if the addin is disabled (versus inactive)
  1. In MSP, go to File->Options
  2. Click on 'Add-Ins' on the left hand menu
  3. Check the 'Disabled Application Add-ins section' section on the right hand side
  4. If the Clarity Add-In is listed in the disabled section, review the Resolution steps of this article


Release: All Supported Releases
Component: MSP


Reinstall the CA Clarity Addin using the below steps:

(Note: The CA PPM Microsoft Project Interface and CA PPM Schedule Connect components do not have to be uninstalled/reinstalled)

1. From Control Panel -> Programs and Features, uninstall the CA Clarity Addin component 

2. In MSP: 

• Go to View > Macros > Visual Basic 
• Expand ProjectGlobal then Expand Modules 
• Delete the modules that start with either CA_ and Niku_ 
• Expand Microsoft Project Objects, Double-click on Thisproject 
• Select everything in the right panel and delete it 
• Save and exit Visual Basic 

3. Navigate to the following folder directory: CA\Clarity\CA PPM MSPInterface\addin and double click setup.exe to run through the install process for the Addin

If the above doesn't help:

  1. Do a clean uninstall of the Clarity PPM MSP Interface using the steps found at: KB000045862.
  2. When reinstalling the interface, make sure the bit level installed of the MSP Interface matches that of MSP.
