Compatibility with MS Office 2007

Hi Gurus,

We are using SAP B1 2005 B with patch level 38.

We have a addon of XL reporter.

We are facing problem of its compatibility with MS Office 2007 as or company has updated Office 2003 to 2007.

When SAP connects the addon of XL reporter version 2.56, it says MS excel is not installed,while its is already installed with version 2007.

Please can you give me the solution for the same?

Thanks in advance.
