尝试使用pywin32打开MSProject mpp文件时出现“项目无法打开文件”

Question

I am using pywin32 to extract data from an MSProject (.mpp) file. Everything had gone well until I installed the Japanese version of MSProject on my PC.

The error message shown as below comes out every time when I tried to open a mpp file by pywin32. Is there any piece of suggestions? Thanks!

I have tried:

• restarting my PC
• repairing MS Office in Apps & Features settings

import win32com
try:
  mppFileName="Project.mpp"
  mpp=win32com.client.gencache.EnsureDispatch('MSProject.Application')
  mpp.FileOpen(mppFileName)
except Exception as e:
  print(str(e))

(-2147352567, 'Exception occurred.', (1004, '', 'Project cannot open the file.', 'C:\\Program Files\\Microsoft Office\\Root\\Office16\\VBAPJ.CHM\\x00', 131072, 0), None)

After changing the file address into the Absolute Address, the problem has gone. That is,

import win32com
try:
  mppFileName="C:/Project.mpp"
  ...
