The "Cannot Place File. Invalid PNG file" bug is BACK in the LATEST RELEASE OF INDESIGN 17.0!!!!!

"Does anyone from the InDesign Programming Team at Adobe ever look into this forum?"

Well, hardly…

Now that it is clear what exactly can cause the issue (other causes can also apply), best report the bug for InDesign 2022 version 17.3.0 at InDesign UserVoice:

https://indesign.uservoice.com/forums/601180-adobe-indesign-bugs

But first let's see if we can find a report that fits your issue.

Found one from version InDesign 2020 version 15.0, that was fixed later as version 15.1.1. In the comments some claim it was never fixed. Hm. I also left a comment and some links to this discussion here and voted for a fix:

Cannot place this file. Invalid PNG file

Nevertheless, it would be good to write a new report.

Hi Pat,

thank you very much for both videos!

Interesting.

Ok. What really helps is to batch save the PNG files from Fireworks again with PhotoShop.

But that would be counter-productive to your current workflow.

Now its clear that Fireworks 8 ( was that really version 8 in the video? ) added some information on top of the pixel data for some images. And obviously that's the reason why InDesign 17.3.0 cannot place the PNG files. Or has problems with them when one opens a document from 16.4.2 in 17.3.0 that contains the placed PNGs. Interesting also to see that image preview resolution makes a difference here.

Perhaps I can place two of your sample PNGs because my laptop's screen is 1280 x 960 pixels and not 4K and above?

Would it work to place the PNGs if the layout window is small?

To answer this: no, it would not help.

Opened my test document from 16.4.2 in 17.3.0 and see the same issues like you do in your video.

If preview is set to High Quality an error message is issued when I open the document.

If there is low quality or normal quality, there is no issue to open the document.

Apart from that: I was not able to export that document to PDF/X-4. Had this error message:

"Found 1 Problem ( 1 error ) with a background task."

"Export: "file name"

> "File cannot be placed. Invalid PNG file."

And all that, even when the preview is showing all PNG images and the Links panel is all good as well.

No missing linked image. Everything's updated.

Of course the same when preview has changed to High Quality:

And to repeat this for all you lurkers:

No issues at all with the same PNG files with InDesign 16.4.2 on the same Windows 10 machine.

"Having the same issue. 

Hi together,

could you attach one sample PNG file that once worked, but does not export to PDF in InDesign 2022 version 17.0 ?

I'd like to test this on my Windows machine where I have all the latest versions of InDesign installed.

Thanks,

We are experiencing similar issue with invalid PNG file error when trying to print or export to PDF. 

Were you able to resolve this? How did you identify which PNG file(s) was/were invalid?

We have not had issues printing to or exporting to PDF in the past. Is it a bug with the latest version (17.1) of Creative Cloud?

Thanks for any feedback or insight you might have.

Hi there,

Sorry to hear about this trouble. I checked on my machine, there are no issues exporting PDFs with PNG files in it. I would request if you could share a few more details to investigate this issue:

• Operating System
• Is the issue related to a specific document? 
• Where you are saving the exported files (Network Drive/ System HDD/ Shared Folder on System/ External HDD)? 

We're here to help!
