Accpac V6.0 Excel versions

SOLVED

We have a customer on v6, moving to 2014 soon.  In the meantime, a workstation using the system now has Excel 2013 on it and the financial reporter won't run.  My guess is that it is an incompatibility issue.  The customer is asking what versions are supported and I couldn't find it in the KB.  Is Excel 2010 the latest supported version to work with this product?
