When performing the installation of the MS Project Integration component on my system (running 64-bit MS Windows 7 Enterprise with MS Project 2013 Professional), I notice that only the CA PPM Microsoft Project Interface x64 and the CA PPM Schedule Connect (x64) are installed.

Okay... So I proceed to manually install the CAClarityAddIn by running the Setup found in C:\CA\Clarity\CA Clarity PPM MSPInterface\addIn folder. The setup runs and completes, but the AddIn is not displayed until I exit the MS Project
Options and then reopen it.
At this point, I shut MS Project down and then re-launch it. Now, I get the following error:

I click "OK" (to remove the error) and select a Blank Project. At this point, all looks good (in MS Project). The CA PPM Integration tab is now visible. But... When trying to "Open in Scheduler" (in CA Clarity PPM) a project by selecting "Microsoft Project [Read-Write]", I get the following error again:

Any idea why this is happening???
Thanks,
Chris
