Microsoft Word will not work on a server on which it is not installed

Turns out that Microsoft Word won't work on a server on which it's not installed :)

I support a program that interfaces with the InSystems Calligo Assembly Engine (or assembly server, depending on configuration) through DCOM using the InSystems assembly link toolkit.

We have, over the years, decided to take advantage of every API that the assembly link toolkit affords, and therefore do our printing through a AssemblyLinkDocument.PrintDoc() method.

As it turns out, the .print() method does a very strait-forward automation of MS-Word to accomplish it's printing, and will therefore not work when Word is not isntalled.

This manifest itself by an HResult of 0x80010105 on the call PrintDoc. Some initial googling of the value indicated that this is what you get when you try to invoke a method on an object that has yet to be instantiated.
