Clarity PPM On Premise Clarity PPM SaaS


  • Project plan will not open in MS Project 2016
  • Symptoms may include:
    • The last time you opened 'ProjectID' it caused a serious error. Do you still want to open it
    • Project dialog box pops up with a list of projects from Clarity
    • User selects the project from the dialog window but it still won't open - Project hangs at writing to xml
    • Or sometimes user gets "An error occurred while openings the CA PPM project in Microsoft Project, please try again"


Release : All Supported Releases



This can be due to a Microsoft Project defect fixed in a later MSP Update. 


  • Ensure you have a supported MSP Update (KB4484345 resolved the issue for one user)
  • It's recommended to upgrade to the latest MSP Update as this will have the most issues fixes since updates are cumulative. 

    • See 11553 - How do Microsoft Project monthly patches impact Clarity PPM?
