MSP Target error or Clarity Addin missing due to wrong bit level

Clarity PPM On Premise Clarity PPM SaaS


When opening Microsoft Project/MS Project (MSP), you receive one of two Target errors where the error line reads either: 

  • Error: Project cannot open the file.
  • Error: Openfromdatabase

Sometimes the CA Clarity Addin tab / menu does not appear at all. After you start MS Project you don't see the Clarity PPM MSP Interface/Integration tab / it's not visible after the installation. Checking the Visual Basic section of MSP, the CA VB components are not showing. You are unable to install the Microsoft Project Connector and Schedule Connect successfully due to this issue.


Release:  All Supported Releases


This is typically due to the wrong MSP Interface bit-level being installed. The MSP Interface bit-level must match that of Microsoft Project. Example, if MSP's bit level is 64 bit, then the 64-bit level MSP interface should be installed.


  1. Perform a Clean Uninstall of the MSP Interface
  2. Reinstall the MSP Interface with the correct version (that matches Clarity) and bit-level (that matches MSP)
  3. This can be installed from Clarity in Home->Account Settings->Software Downloads:
  • If your Microsoft Project Bit level is 32 bit download Microsoft Project Interface (x86)
  • If your Microsoft Project Bit level is 64 bit, download Microsoft Project Interface (x64)

See MSP bit level installed - steps to determine for more details.
