Currently, the Plastic SCM installer provides an option to include plugins for various IDEs as well as Office.

The Office Plugin support is provided for 2003, 2007, and 2010. Noting that the year is 2016, and that two releases of Office have occurred since then, the plugin should be updated to work with the latest versions.

Additionally, the Office Plugin doesn't have quite the same "polish" and "style" that the rest of Plastic has when running on Windows, so it could use some touching up.

Finally, if this isn't a priority - and since it really exists to integrate with Plastic rather than is Plastic - consider releasing the code for the plugin as an open source product, allowing the community to contribute to its updates, maintenance, and enhancements.
