Hi Stephanie,
In my case, I had to create a new data & value in the registry that I have include into the MST file generated through the Adobe Customization Tool:
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown]
"bUsageMeasurement"=dword:00000000
And it works like a charm.
I noticed that vdobhal mentionned "HKLM\Software\Policies\Adobe\Acrobat Reader\2015\FeatureLockDown" I don't know what's the difference and if I'm right or wrong. Anyone has an explanation?
