PRB: PDF attachments fail to render in Zetafax Client when using Adobe Reader XI Print ZTN1961 ID: ZTN1961 This Zetafax technical note applies to: Zetafax 2012 Adobe Reader XI Symptom After attaching a PDF document in the Zetafax Client fax wizard and submitting it for sending, the fax immediately fails with the system tray pop-up error showing “Failed to send”. The server monitor displays the following: Cannot convert PDF; Rendering Add-on not licensedError appending file … File attachments which fail to convert on the client side will be sent to the server as part of the fall back mechanism. Customers who have purchased the Rendering Add-on would not have this problem. Resolution There are two suggested methods to work around this issue, the options are as follows: Install an earlier version of Adobe Reader. Version 9 and 10 will render PDF attachments successfully on the client side. Purchase the Rendering Add-on so PDFs are rendered server-side. This add-on has the added benefit of supporting many more file formats over the standard types - http://www.equisys.com/technotes/ztn1261.htm Status This has been identified by Equisys as a problem with the software versions given above.
