g9 791 geforce experience

hello,

i have a problem with the geforce driver.

i make the install on a clean windows 10 version (1703 family).

I install all the driver present on the acer website (verison of 2017/06/26)

I install the driver nvidia 385.69-notebook-win10-64bit-international-whql from the nvidia website without the geforce experience.

I install after the geforce experience GeForce_Experience_v3.9.0.97

When the install is finished, i restart my laptop.

When i launch the Geforce Experience, i see a windows with the geforce colors but nothing other... normaly i need to see a logon page and after all my games...

What can I do?
