problem to configure A4 & Overbridge with Ableton: A4 VST does not appear

Hey everybody

My problem is in the title: I have tried many times to configure my elektron gear with ableton, with differents upgrades. everything goes good, but when I open ableton and I try to find the elektron VST… Nothing!!

My Ableton is actually on 10.1 version
My Elektron is on 1.40 version. (latest version)
My Overbridge is on 2.0.24.11 version (latest version)
My computer is on win 10, x64 bits

If someone could help me it would be so great!

thank you for reading me, and bye!
