Hello Kurio71, The method described in the KB is shaky at best, but it was the best we had at the time. There is a relatively inexpensive third-party add-on you can try (it has a 30-day free trial) that enables ACT! 2010 and Office 2010 compatibility: http://www.designr1.com/shop/act-word-2010/
Not sure how it will work with the AU version.
Note: Effective 6/1/13, Sage no longers provides support for the Act! software. This is now provided by Swiftpage.
