  • After installing the MSP Interface and CA PPM Schedule Connect for Clarity, I am getting a VB Run-Time Error '53' when opening a project to Microsoft Project (MSP).
  • Clicking on Debug for the error the following was highlighted in the code:

MsgBox Niku_Api.mspGetMSPLocalizedString("IDS_MSPINT_BADVERSION")

  1. Navigate to project in Clarity PPM
  2. Click the "Open in Scheduler" drop down on the Project Properties or Tasks tab
  3. Select Microsoft Project [Read-Write] or Microsoft Project [Read-Only]
