How to set XE8 FD Explorer ini file Setting location

In XE8, you can find that the ini file setting location has been set as following (you can find this in the FireDAC Explorer):

Connection definition file = C:\Windows\FDConnectionDefs.ini and 
Driver configuration file = C:\Windows\FDDrivers.ini

The problem is C:\Windows usually not allow for file write and that cause a problem, I CANNOT create any connection definitions.

These settings are readonly, though there is a checkbox for you to set default.

The only way that I can find to modify these location is by REGEDIT.

You can find the settings in HKEY_CURRENT_USER\Software\Embarcadero\FireDAC. Just modify the value for ConnectionDefFile and DriverFile accordingly and you will be able to save the settings.
