Unable to cast COM object after deployment

Question

 hi all,

I had created a Word Add-In which runs fine on the Development machine (XP ,with Office 2003 SP2) , but when I deploy the installer onto a different PC it throws up an error while opening a file , which is says

"Unable to cast COM object of type 'System._ComObject to class type Microsoft.office.Interop.Word.ApplicationClass'. COM Components that enter the CLR and do not support the IProvideClass info.

Any help will be great !!
