What should I do if there is no Southeast Asian language pack installed in that language directory?

I just installed the office computer. It can't be installed without Southeast Asian languages, but it has been solved now.

This is a stupid way,

First, in the control panel-regional and language options-language-then install Southeast Asian languages will be checked.

The next step is to install, click browse, and the files you need will be automatically displayed during browsing. Some of these files can be found on the local computer, and you can run them one by one by searching (on disk C), but some files can't be searched, so you go to a website to download them. This website is called Dangdang,,, and I just did it so foolishly.

I don't know if there is any other good way,

It takes a lot of time. It takes about 1 hour to get ready. Be patient.
