CUDA 9.1.85 win10_64 NVidia installer failed

I’m trying to install CUDA 9.1.85 on win 10 and get this error:

Checking system compatibility
“NVIDIA Installer cannot continue” “This NVIDIA driver is not compatible with this version of windows”
Then the only option is to close the installer.

my system data is:

Windows 10 1709 - the latest update
Installed NVIDIA driver is 390.77

Your help is highly appreciated
