Unfortunately, based upon our current research, there appears to be no workaround to the incompatibility issue between the new OS 10.10 and the Microsoft Office Suite for Macintosh. The only options at this time are to either roll back to the previous OS Maverick 10.9.5 or to wait until Microsoft releases a patch for the Yosemite OS. Should you opt to roll back to the previous Maverick OS 10.9.5, we highly recommend acquiring the assistance of an IT professional to assist you in that matter.
