Acrobat Pro (24.003.20180) slow load times after upgrading to Windows 11 24H2

[montanarane1094]

I am running the current version of Acrobat Pro (24.003.20180) and it now takes 24 seconds to open a pdf file after upgrading Windows 11 from 23H2 (2023 update) to 24H2 (2024 update OS Version 10.0.26100.1742).  If I modify Acrobat Pro by turning off "Run in AppContainer" under Security (Enhanced) in Acrobat preferences files load in 1 second.

 Same goes for me.  After latest Windows Update,  It takes forever to open a PDF file.  Surely Adobe is aware of this?

same here starting to see more PC's with this issue

I have the same issue and I don't think Adobe is aware of it

The fix is to turn off Protected Mode in the settings

Hi @Andrew31956183kamv,

Hope you are doing well. Thanks for reporting this.

We are aware of the issue and working on a fix.

While turning off AppContainer is a temporary fix, we are working closely with Microsoft to get to a permanent solution.

We request your kind understanding and patience while the team releases the fix in the upcoming update.

Re slow startup after Win 11
"The fix is to turn off Protected Mode in the settings"
Thanks, Andrew, I wish I had found this sooner - finally back to "normal".

Hi @majerovy,

Thanks for writing in!

Instead of completely disabling Protected Mode, you can try unchecking the Run in AppContainer checkbox.
