excel - Using Office 2007 PIAs with Excel 2002 (Primary Interop Assembly)

Question

Is this possible?

My app references Excel 2007 Primary Interop Assemblies. Can I install these on a PC which has only Excel 2002 (XP) installed?

Or do I need the Office XP PIAs?

In that case, do I need to modify my program to reference the old PIAs?

简短的回答似乎Interops是不向前兼容，即它们不会在部署环境中使用低于最初目标的版本化程序集。为了以较低版本为目标，您应该明确引用较低版本的程序集。
