Windows 10, Word 2013 under Parallels 13 can't run docm: permissions?

I'm trying to run a docm (Word document with macros) in Word 2013 in Windows 10 under Parallels Desktop 13.0.1, Mac Sierra 10.12.6.
I have set the security in Word so that I can run macros, and it starts running, but then gives a VBA Compile Error. When I click on the Help button, it reports:
Your organization's policies are preventing us from completing this action for you.
My folders are all read-only from the viewpoint of Windows. I turn off read-only under Windows 10, but the next time I check Properties, Read-Only is back on.
I adjust permissions under the Macintosh side of things, but folders are still read-only under Windows.
This is a private machine and I've adjusted permissions to the maximum allowed (full access, read-write for all levels). I'm on with Admin status under Windows, but I can't get read-only to turn off.
Thank you for any help.
