unable to reconfigure MySQL 5.7 (no replies)

Hi,

I am running MySQL 5.7.17 x64 on Windows 2008 Server.
I have downloaded "mysql-installer-community-5.7.17.0.msi" to check my setup.
When I launch the installer, it requires to reconfigure "MySQL 5.7".
When I click "reconfigure" and follow the wizard until the "Apply server configuration" tab and click on "execute", reconfiguration hangs up on "adjusting windows service" and log ends as follow:

Beginning configuration step: Adjusting Windows service [if necessary]
Attempting to grant Network Service require filesystem permissions.
C:\ProgramData\MySQL\MySQL Server 5.7
C:\ProgramData\MySQL\MySQL Server 5.7
Ended configuration step: Adjusting Windows service [if necessary]

So it sounds I have a filesystem permission issue on:
C:\ProgramData\MySQL\MySQL Server 5.7

How can I solve this, can't find no clue in online doc.
