word转pdf遇到问题（提示库没有注册）

代码如下：

#word转pdf
from win32com.client import Dispatch,constants,gencache

docx_path=”洛神赋.docx”
pdf_path=”洛神赋.pdf”

gencache.EnsureModule(‘{00020905-0000-0000-C000-000000000046}’,0,8,4)

wd=Dispatch(“Word.Application”)

doc=wd.Documents.Open(docx_path,ReadOnly=1)
doc.ExportAsFixedFormat(pdf_path,constants.wdExportFormatPDF,Item=constants.wdExportDocumentWithMarkup,CreateBookmarks=constants.wdExportCreateHeadingBookmarks)
wd.Quit(constants.wdDoNotSaveChanges)

#错误：
但是运行之后出现以下错误 不知道怎么解决：

#尝试的解决方法：
下载MDI Jade 6

然而没有成功 不知道还有什么解决方法
