ADOBE Reader DC Disable "enabler fast find"

[rico2490553692kw]

Hello,

I would need to disable the "enabler fast find" by a GPO for all users.
The registry key is in Hkey_USERS :
HKEY_USERS\xxxx\SOFTWARE\Adobe\Acrobat Reader\Search\cOptions\bEnableBGIndexing

Thanks in advance.

For information I tried without success :
REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\FeatureLockDown"
bEnableBGIndexing=0
