Urgent help needed for project! Word Application Scope

Hi I have encountered this error, my microsoft is 2004 version 64-bit, I can’t really reinstall it as 32-bit due to work reason, is there other method to solve this? Thank you!

Hi, I have just googled that and this is what I have found, hopefully it will help you. https://answers.microsoft.com/en-us/msoffice/forum/msoffice_word-mso_other-mso_2010/unable-to-cast-com-object-of-type/34efcd57-e819-4a83-9cdd-501ab15b0971?auth=1

Edit: If this is happening on the word application scope the only thing left to do is automating the user interface of word.
