Having error when open PDF files that embedded in excel

Hi,

I have save my emails to PDF and embedded it in the excel sheet. I always received several error message when using the latest Acrobat Standard. But when I uninstalled the Acrobat Standard and installed Acrobat Reader. I got no problem when opening it.

------------------------------------------------------------------------------------------------------------------------------------

Error message received.

 1. an error exist on this page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem.

2. There was an error processing a page. Operation or data is too complex.

-------------------------------------------------------------------------------------------------------------------------------------

I don't think that the PDF files is corrupted as I do not have issue when opening via reader and this issue do not affect me but also my others colleague that using Acrobat Standards.

Thank you,

Azhar
