acrocef_1 folder is already generated at the time of new installation
At the time of new installation, the repaired installation folder of
"C:\Program Files\Adobe\Acrobat DC\Acrobat\acrocef_1 "has already been gene.
Normally, this folder is a recognition generated during installation repair,
but why does it already exist?
Also, the process that actually starts uses the one in that folder
("C:\Program Files\Adobe\Acrobat DC\Acrobat\acrocef_1\AcroCEF.exe").
