Tip: How to correctly select the file you need
1 If you know MD5 value of the required files, it is the best approach to make choice
2 If you do not know MD5 value of files, you can choose the appropriate files by adopting the following three steps:
(1) View the operating system version. (Method: Click "My Computer" on the desktop-> "Properties" to view the operating system version)
(2) If your original file is just corrupted but not lost, then please check the version number of your files. (Method: Click your original file, and then click on the right key to select "Properties" from the pop-up menu, you can see the version number of the files)
(3) Depending on the version number of your existing operating system, and version number of the files, you can select the corresponding files from the list below to download the required files.
If you still can't find the file you need, you can leave a "message" on the webpage.
