4.3. Does the e-mail recipient need to have Attach Plus to view their attachment?

No, they just need to be able to open the file format of the attachment (PDF or ZIP).

If e-mailing an encrypted PDF file, the recipient will need Adobe® Reader 5 or above to view it (because Attach Plus uses 128 bit strong encryption). The viewer is available for download from Adobe® for free at Get Adobe Reader

If e-mailing an encrypted ZIP file, the recipient will need Winzip 9 or higher to open encrypted ZIP files. A trial of the latest version of Winzip can be downloaded from www.winzip.com.
