Adobe applications asking for Serial Number

[TDB222775042eqx]

It looks like a license has expired in our organization.
The license information on the admin portal is still valid until late 2023

A lot of older Adobe installations do not work anymore, upon starting the application e.g. Adobe Acrobat, the user is prompted for a Serial Number. But also the most recent versions.

• We are using the most recent version (MSP) of Adobe Acrobat, but also other Adobe application are affected, and somewhat older versions
• We have run RemoveVolumeSerial.exe on an affected machine, no positive result
• The user has a valid license (adminconsole.adobe.com)
• This information has not helped us
• The user keeps getting serial dialogs like this:

Note, the dialogs are different, but they alle have to do with signing in or entering a serial.

Business Impact is very high

1: Close all the Adobe processes from the Task Manager including the process related to the Creative Cloud desktop app.
2: Go to Registry Editor to the location HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe Acrobat\DC\Activation
Create a new registry key at the below location -
Path : HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe Acrobat\DC\Activation
Create a new DWORD: IsNGLEnforced
DWord 32 bit, set the value to 1
