2 different Device Activation Limit Messages

Hello,

Firstly, please could you confirm the kind of package you are using to install - is it a legacy-style Acrobat package with a subdirectly in the ZIP file that's called "Adobe Acrobat", or a package generated from https://adminconsole.adobe.com/ containing Acrobat? In the latter case, the package should be installed via the setup.exe in the "Build" directly, not the one within the Acrobat subdirectory, to ensure the licensing information and the various shared components (Visual C++ Redistributables etc.) are installed as well as Acrobat. You can still use MST Transforms files with this method.

Secondly, it might be the case that you have the old AMT licensing service enabled on some of these systems; you can check this as follows:

Old licensing mechanism:

Windows registry:

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Adobe\Adobe Acrobat\<version>\Activation]
"IsAMTEnforced"=dword:00000001

mac OS:

MAC:
/Library/Preferences/com.adobe.Acrobat.Pro.plist

<dict>
<key>FeatureLockDown</key>
<dict>
<key>IsAMTEnforced</key>
<true/>
</dict>

The alternative (and default) is to enable NGL by either deleting the aforementioned settings, or setting the following options to enable the new licensing mechanism - these should not be necessary, but you can set them to ensure this is enabled:

Windows:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Adobe\Adobe Acrobat\<version>\Activation]
Create a new 32-bit DWORD: "IsNGLEnforced"=dword:00000001

MAC:
/Library/Preferences/com.adobe.Acrobat.Pro.plist

<dict>
<key>IsNGLEnforced</key>
<true/>
</dict>

Sincerely,

Dominic
