QB Issue Resolution:

Please note that click to Run versions, Trial versions, and Starter Edition of Microsoft Office or Excel do not support the integration components used by QuickBooks (Click to Run Office is an online enabled, but limited edition of Office). If you are using one of these versions, the option to export to Excel is grayed out and unavailable. Please see the Microsoft Office 2010 FAQ for more information.

Incase you are using the locally installed version of Office, running repair would be of help. See the instructions for Windows 7/Vista.
Click the Start menu and choose Control Panel.
Click Programs and Features.
Click the Office program you want to repair, and then click Change.
Choose Repair and reboot when complete.
Try exporting the report in QuickBooks.
