This does not sound like an osTicket Awesome issue to me.

I would suggest updating your zip software and trying again.

Or, using this link, you can download a utility from Ninite that will silently install the latest versions of 7Zip, PeaZip and WinRAR.

I feel confident that one or all of them will open the zip.

If you would like to rule out the possibility that this is an osTicket Awesome issue, please press SHIFT + O before downloading the zip. Doing so will transport you to a copy of vanilla osTicket running your same database.

Please let me know if this resolves your issue or not.

Hi Steveland,

I tried with vanilla. After I cliked the Print/Thread+Internal Notes+Attachments button, opening a new blank page, and happening nothing.
The PeaZIP said, this is not a ZIP file.

Hi @nandor,

Sorry, I didn't quite understand your last message.

Are you saying the same issue occurs in vanilla, or no?

i have the same issue ost awesome 1.16.3 has this bug, but osticket 1.16.3 does not and works as expected.  when you attempt to download the zip with "Print/Thread+Internal Notes+Attachments"  the .zip is corrupt.  If you open the resulting .zip file in notepad, it seems to actually be a pdf file.

EDIT:  the issue also happens when using the original osticket inside the osticket awesome, but like i said a clean install of osticket 1.16.3 works properly.
