Robohelp 2015 won't let me import a Word document

People,

I have just installed Robohelp 2015 (version 12.0.0.306).

When I try to import a Word file to create a new project, it fails and I see the message:

"The Import Word Document Wizard cannot locate a supported version of Microsoft Word. Please install Microsoft Word 2000 or newer."

But I am using Word 2016.

Is this a known compatibility issue?

Thanks in advance,

MAM
