Basilisk ultimate / Synapse not able to install

Hello, and happy new year !

 

I just got a basilisk ultimate mouse, but I’m having troubles for the setup :

  • The mouse works properly when it comes to moving and clicking, either cabled or dock-linked
  • Additionnal buttons, including 4, are not recognized. They don’t seem to send any output at all when pressed, as I have been unable to manually set them in games.
  • After installing synapse, here is the situation
    • Mouse is properly detected by synapse 4 (a tab is created)
    • It can’t seem to install it. It downloads the files, but I get a “installation failure” message.
    • I tried uninstalling synapse, the mouse, deleted the pilots, etc.

In advance, thanks a lot <3
