Acrobat PDF File Format is having difficulties. Bad parameter.

[treefrog designs]

Does anyone know why Adobe illustrator is suddenly giving me this message on files... preventing my saving them...? ANyone else had this recently? It has only happend since yesaterday....

[Monika Gause]

Does this happen saving or when importing them?

What kind of PDF is it? Which application created it?

Which version and system are you on?

What has changed from before this happened?

[treefrog designs]

I'm on macOS Ventura 13.2.1 
Illustrator 2023 27.3.1

Problem happens when trying to save some illustrator files as a PDF from the Ai version of the file.
Problem also happens when trying to just save the Ai file and I have the "Create PDF Compatible file" checked.

File saves ok when box is unchecked...

Nothing has seemingly change since yesterday, when everything was working fine.
Unless updates have automatically happened in the background...

I was saving Ai files as PDFs fine yesterday.

[Monika Gause]

I have just tried it (just in case) and it worked for me. But I'm also still on Monterey.

What's inside your file? And if there are fonts, then which ones? Any special color management settings?

Where do you save your files?

[kevin stohlmeyer]

Hi @treefrog designs do you have special characters in the document name or foreign language fonts live in your document? I've seen similar issues with accents in the file name or properties Title.

[treefrog designs]

Hi, no foreign or weird characters in the files names... I'm used to these issues too, so always careful with my file naming 🙂

[kevin stohlmeyer]

HI @treefrog designs did you check file info and the Document Title metadata?

We've had this break PDFs too.

[dennisboltphcs]

Me too! I am on new mac with newst OS and newest version of AI. I updated AI today and after doing that this same thing happened when trying to save existing files as either AI or PDF.  I restarted, reset prefs etc. I downgraded back one version of AI and it works fine, so its the newet version that is causing it on my mac.

[treefrog designs]

Aaah so this could be a bug with the latest version...?

[kevin stohlmeyer]

Hi @treefrog designs @dennisboltphcs can you both check to see if Illustrator is listed under Apple System Prefs/Security and Privacy/Full Disk Access?

[treefrog designs]

Thnaks, Just tried this but still having same error message...

[kevin stohlmeyer]

@treefrog designs sorry if you posted already - what preset are you using when saving PDF? Have you tried using PDFX1-a or another preset without modifications?

[treefrog designs]

Anyone got any solutions for this yet?
It's driving me nuts.
Most of my files are fine but some just won't save even as Ai let alone PDFs...

[kevin stohlmeyer]

Hi @treefrog designs you didnt reply to the last post. What happens if you save as using a preset (example PDF X1-a) and do not modify?

[treefrog designs]

Sorry, it happens if i'm just saving an Ai file as an Ai file now.
If I uncheck the "Create PDF Compatible file" at the time of saving it works... but then that doesn't really help me as I need to save it as a PDF too.

[kevin stohlmeyer]

A new wrinkle - now you cant save Ai files? Where are you saving to - local HD or external, server, cloud synced folder, etc?

[treefrog designs]

Tried saving to external HD aswell as my local HD. Not tried cloud.

[kevin stohlmeyer]

Hi @treefrog designs keep saving to local to avoid extraneous issues.

Check your Apple System Preferences/Security and Privacy/Full Disk Access is Illustrator listed?

[treefrog designs]

Yes I tried this previously but made no difference...
It must surely be something to do with PDF settings / compatibility in illustrator if saving works when I uncheck that "Create PDF Compatible file" ?

[kevin stohlmeyer]

Could be - another user noted rolling back to the previous build resolved. Not sure what specifically could be causing this on your machine. You could try going to

Logging into the page, then click the chat pod at the bottom right. Type "AGENT" to get a real person - they can schedule a 1:1 with an engineer to remote in and check your specific setup.

I faced the same problem as you.. i tried everything.. but to no avail until i proceeded to downgrade one version lower.. then everything is possible again.. 

[Kamila28790203vzfr]

Can you tell me which version exactly you went for ? I have Windows 10 and have the same problem 😞 

[dennisboltphcs]

Downgrading the version of Illustratgor solved it for me. I was on newest and just went one subversion back.

[Kamila28790203vzfr]

1. Really? I have Windows 10, went 1 subversion down without change - still unable to safe pdf file to my local drive 

[RichGFX]

I encounted this today when saving an .ai file which didn't allow me to save. In the save dialoge i unchecked "Create compatible pdf" and it allowed me to save my ai file. i am however still getting the error when saving as PDF.
