Assuming that the project is open in Policy Modeling, then something is interfering with the communications between Word and Policy Modeling. This could be other add-ins (like Foxit) so try disabling that to see if the issue disappears. Also confirm if the project is on a local drive or a shared network location.
Thanks for the help . Uninstalled Foxit and confirmed project in in local drive . But still same issue .
I hope you are using 64 bit MS office, please try with 32 bit MS office.
32 bit MS office resolved my similar error.
Hope it works for you as well.
