You are aot able upload the Project Plan (.mpp) and the CA ppm Integration tag/tab is not available/missing. The Addin is showing as disabled, and we are not seeing any of the modules in Microsoft (MSP) Visual Basic when reinstalling the addin.
Note: We use a silent installer to install the MSP Interface
Release : All Supported Releases
Component : CA PPM MICROSOFT PROJECT (MSP)
This issue can be related to an issue with a silent installer/package
Install the MSP Interface directly from Clarity versus the custom / silent installer.
If the above works, this indicates an issue with the silent installer, reach out to the team who created the package to look into issues with the package
