Checkbox control in word document rendered as radio button on pdf

I have a word document that contains a few checkboxes. On development machine(windows xp), the Aspose.Word renders it correctly when converted to pdf. However, in test system (windows server 2003), it renders the checkboxes as radio button. Please see attached docx, and two pdf files.

Hi
Thanks for your request. Please make sure that Wingdings 2 font is installed on the PC where you perform conversion to PDF. If not, please try to install Wingdings2 font. This should fix the problem. Please let me know in case of any issues.
Best regards,

Thanks!
Installing the font fixed it.
