DengXian font is a Chinese (Simplified) supplemental font that is shipped with Ms Windows and other MS Office programs.
The error you're getting (in my opinion) seems to be related to a licensing restriction.
Either the user will have to manually download and install this font type for the intended Windows version from here:
https://www.microsoft.com/en-us/download/details.aspx?id=49113
More additional info here: https://docs.microsoft.com/en-us/typography/fonts/windows_10_font_list
Or have him/her go visit this link: https://docs.microsoft.com/en-us/typography/font-list/dengxian
and scroll down to the section "Licensing and Distribution" to see if postscripting or distilling is something that is simply not allowed:
