How to reliably enable new experience in Adobe Acrobat Pro

[DmitryZ]

Adobe recently introduced new interface for Acrobat Pro: https://helpx.adobe.com/acrobat/using/new-acrobat-experience.html. However, I cannot enable it despite all conditions are met: x64 version, English language, no third-party plugins. I have two questions:
1. How can I reliably enable and disable new experience in latest version of Acrobat Pro?

2. How can I relocate the custom plugin menu to a better location with new experience enabled? Currently just one click is needed to open it. With new experience three clicks are needed: Hamburger menu icon => Plugins => plugin name. I'm wondering that regular user won't be able to find the custom plugin menu.
Thank you,

There is a DWORD registry setting bEnableAv2 that should be set to 1 in order to enable new look. Here's the corresponding registry path: HKCU\SOFTWARE\Adobe\Adobe Acrobat\DC\AVGeneral. The setting works for Acrobat Reader too (with adjusted registry location). Still have a problem with custom plugin menu placement.

For some reason the registry setting bEnableAv2 works on physical machines, but doesn't work on virtual machines (I'm using Hyper-V). The license is the same -- Adobe Enterprise.

There is also a menu item for enabling/disabling the new UI.

Don't think you can relocate the plug-ins menu. Sucks, but that's how it goes.

Looks like new look is no gone,  bEnableAV2 does not work.

Although this setting no longer controls using the new UI, it is essential to turn it off to prevent Adobe Reader crashing if you close it shortly after opening a file (within a few seconds). If you wait longer before closing there is no issue. If you open a PDF, glance at it and close it again quickly, the version of Adobe ready deployed in early 2024 always crashes. Although Adobe claims it cannot find the issue, someone posted registry entries to fix this, I tested them and this is the one needed:

[HKEY_CURRENT_USER\SOFTWARE\Adobe\Adobe Acrobat\DC\AVGeneral]

bEnableAV2 = 0

Looks like Adobe didn't fully remove the new AI feature and it crashes if you close Adobe Reader while it is still looking for it even though it is no longerthere, unless you have turned that feature off.
