"unknown device" error in ST Link Utility

When I try to target->connect in ST Link Utility I have an error "unknown device" with disco L4, disco F7 and nucleo L4.
With nucleo L0, the connection is good, but I have the message "Device family : unknown device".
With disco F0, disco F3 and disco F4 it's OK.
The PC is Windows7 64 bits, the USB driver is up to date, and AC6 SW is installed.
On PC Vista 32 bits without AC6, all is OK.
Any idea?
