Passolo 2015 Professional fails to load the Microsoft .Net Parser: "Requested feature is not available".


Did a fresh install of Passolo 2015, with a Professional license.

In the Add-ins list, I get an error on the Microsoft .Net Parser: "Requested feature is not available":

What am I missing??

Ran Passolo update to latest version: 15.1.371.0.

Have .Net Framework versions 1 thru 4.5.2 installed.

Functions under license in "About Passolo' cite the .Net Parser (but grayed out).

Severe problem that needs resolution!
