"There is no copy of Word 2000 or later installed on the server......"

All,

Running CM-13 under the Communications module/Letters a users tries to add a new Letter and gets the following error message, (see attached) "There is no copy of Word 2000 or later installed on the server......"

Office is in fact installed and on the server and this is a localized (user) problem.  Additionally the PC, it's configuration including IE, Active X, Java and Registry/MSWord6 issues have all been checked and are correct.

Anyone have additional knowledge.

Thanks in advance
