Welcome to the ACT! Community. Unfortunately, there are no versions of ACT! than can integrate with the 64-bit version of Office and no patch or add-on that can force compatibility. ACT! can only integrate with the 32-bit version. Most users do not need the 64-bit version of Office, unless working with very large spreadsheets. See this article from Microsoft: http://officepreview.microsoft.com/en-us/support/choose-the-32-bit-or-64-bit-version-of-office-HA102...
You can uninstall Office 64-bit and install Office 32-bit with no loss of data, and no noticeable change in performance.
Note: Effective 6/1/13, Sage no longers provides support for the Act! software. This is now provided by Swiftpage.
