But when I run NVDA in PDF on our system then work fine because there are already a preference setting, but once I transfer the pdf file to another system then open in Acrobat Reader, no working NVDA, there is required setting once again in every Acrobat reader, then will it work.
I am not sure if it is the right approach to apply the setting manually for end-users. Please suggest.
