When I select “Edit PDF” option, the “All Tools” pane disappears.

This issue seems persistent.

I’ve tried looking at the view/show settings.

Running a repair on the installation.

Uninstalling and Reinstalling Adobe Acrobat.

Can someone please help or provide some suggestions?

Thank you,

Hello @Old_m8

Thanks for your patience and cooperation on this.

The patch is available with the fix 26.001.21691, Planned update, Jun 25, 2026. Please install the latest build of Acrobat from Menu (Win) | Acrobat (Mac) > Help > Check for updates. Restart the machine after installing the updates, and check the performance of the app.

Let us know if you experience any issues after installing the latest build

Regards,

Anand Sri.

Hi All!

Thanks for your patience and cooperation on this.

Please try the following suggestions, and let us know if this fixes the issue for you.

Admin Notes: Ensure you are connected to the internet. Before you try registry editing or even if you are using mac machine. Close Acrobat, try restarting your machine. Launch Acrobat and try again.
If the issue is reproducible let us know. The issue ideally should get fixed after restarting your machine.

Please note: Create a backup of the registry settings before making any changes. To create a backup, check this article: https://support.microsoft.com/en-us/topic/how-to-back-up-and-restore-the-registry-in-windows-855140ad-e318-2a13-2829-d428a2ab0692

Go to the registry location: "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown"
Right-click on the right blank space > select New > DWORD 32-bit value.
Rename it to: bGenCoverPagesLabelStrings
Right click on the new value > Click Modify > add the value as ‘1’ (numeric one)
Restart the Acrobat and the machine and check the performance.

Let us know if you experience any issues .

Regards,

Anand Sri.

Quick command to run as admin for the key for those skimming this:

reg add "HKLM\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown" /v bGenCoverPagesLabelStrings /t REG_DWORD /d 1 /f

Make sure Adobe is updated prior, as it breaks it further.

I opened a ticket with Adobe - can confirm the registry entry did fix our systems.

Here is their response:

I wanted to address your query regarding Acrobat sidebar issue. I would like to inform you that this is a known bug. This is raised at the highest priority with Engineering team. The team has started to roll back the feature that led to the issue. It will take effect tentatively by tomorrow.

To mitigate the problem at the current state, you can create the following registry -
Path- Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown\
Dword - bGenCoverPagesLabelStrings
Value - 1

If you can wait till tomorrow, it will be resolved automatically. No intervention needed.

Happening for my company as well. Seems to have started at least yesterday (possibly earlier). Any update on a fix would be appreciated.

Same, good number of random users. Disabling the new view is our current work around.
