After installing the Microsoft Project Integration and all of its components, Microsoft Project (MSP) throws the following error: Run-time error '53' File not found: caMspXml.dll
This error message can occur if there is a mismatch between the bit version of Microsoft Project and the MSP Interface.
Uninstall the incorrect bit level of the MSP Interface, then install the correct bit level of the Interface that matches the MSP bit level
Note: It's recommended to do a clean uninstall if you still run into any further issues. See steps at: Clean uninstall of the MSP interface
2. Reinstall the MSP Interface with the correct bit level. This can be installed from Clarity in Home->Account Settings->Software Downloads:
