Cannot save reader extended pdf in diff ver & platform acrobat

[SFAWai]

Our company generally create pdf forms on Adobe Lifecycle CS2 . 

And after finish we using Adobe Acrobat save reader extended pdf to let Adobe reader can save form .

Today we cannot save  save reader extended pdf  on screen cap after testing on PC ( Win 7 ) Acrobat X ,XI and DC also cannot (As attached screen cap ) . Also cannot save on iMac 10.15.x Adobe Reader DC .

The ridiculous thing is : We using the file can normal save extended pdf 3 months ago and 6 months ago , these files also cannot save extended pdf today . 

Also we testing pdf on Acrobat DC create pdf form that also cannot  save extended pdf today .

These computer are offline , and file testing on different computer , so I cannot find cause . Can help me ?

What happens when you save the filled form?

[SFAWai]

Hello , that is not tested .

But do you think it is ridiculous that the files can work in normal procedure 3 months ago and cannot now ? 

We have no change in Acrobat version , no change in setting , no extra plugin . 

[SFAWai]

Here is the most simple pdf form created on Acrobat only .

It also cannot save extended pdf today as the attachment . 

Attachment also show my iMac Mac OS version and Acrobat version . 

Can anyone also testing for finding solution ?

Exactly the same thing is happening among us.

When I make a pdf form, it can't save exteded pdf.

"Reader extension cannot be not available."

Please help us!

[neth893]

Solution! Please unistall Acrobat DC and reinstall it again.

[Bernd Alheit]

You don't need an extension to fill and save the form.

Same problem here in Australia

We have been using Designer ES2 and Acrobat Pro X (10.0.0) for the last 10+ years without problem. Today, on multiple computers running the same software version we are getting the message " This document can not be Reader Enabled" on new and pre-existing documents! Tried on Windows 7, 10 and 11.

Just spoke to Adobe on the helpline but official support has long ended! Only suggestion was to join the discussion on this forum.

Out of interest I downloaded the latest Adobe Acrobat Pro Trial version (need paypal or credit card to get access to the 7 day trial!!). I can confirm the latest version works.

Akward situation since features have been removed from a product that has already been paid for. 

Hopefully an Adobe representative sees this forum and reports it to their software team for a fix

[Test Screen Name · Accepted solution]

Yes, Acrobat Pro DC (latest version) is the fix. Described here. https://helpx.adobe.com/acrobat/kb/reader-extended-pdfs-and-adobe-root-ca-expiry.html

There is nothing to report, it is not a bug. There will of course be no fixes to Acrobat X, XI, or 2015. Adobe take support seriously, especially the stated date of end-of-life. It would hardly be fair to the people who did pay for upgrades if they supported it willy-nilly for people who want to stay with ancient software and didn't pay. Or so it seems to me. No, breaking it wasn't ideal.

[SFAWai]

Yes , Actually I wish to know the cause . Use new software is not solution because computer and sofware is not free . 

In the view of programmer , I think Acrobat X or Adobe CS6 std have bug that will trigger on Dec 22 or otherwiese Yr. 2023 . 

If Adobe take no afford to fix bug . Can they provide us new computer , new version Acrobar and Lifecycle on Free ?

I have the same issue. It worked in December 2022, and didn't in January 2023. I didn't update anything, even reinstalled.

For others, I'd recommend an alternative at this point to save time and hassle. Ashampoo makes a decent PDF Editor on sale for $30. But regardless, breaking the paid software without any fault of user is Adobe violation of  its own EULA. Anything beats the subscription and tbh, the stability of Acrobat has been shoddy for years.

[Daniel27871203nx6a]

So it's confirmed the latest Acrobat version resolves this problem, however does anyone know or can confirm if Acrobat Professional 2020 has the reader extended, save function? I'm asking this question as my IT department only have purchasing options for the 2020 version as its the last version to purchase outright without subscription fees

My company finally solve problem tempoary by save extend pdf on Actobat DC ver. 2022.003.20281 on iMac 10.15.x  . 

But as I said , it is not solution , what happen if we have not new iMac ? We will lost business and cannot answer client request ! 

If there have any bug trigger on unknown time , do we will see software cannot use in someday ?
