# local (Chinese) help documents does not respond initially using ? or?

One of my Chinese friend's MMA12, running on Windows 10 Pro X64, does not respond to help documents when ? or ?? is used.

We can access the local help documents by clicking the wolframe document from the menu.

Now, the ?Plot and ??Plot would respond and give you the local option...

Everything works fine after we have launched the wolframe document, now even this would work...

**MAIN question ** Why wouldn't it work in the first place?? We checked in the Preference but couldn't see anything unsual...
