Left Handed DeathAdder 3.5G - Can't Configure

I’m installing this mouse on a laptop that was re-imaged and all my programs wiped. Downloaded and installed Synapse 2.0. It recognizes the mouse but I am stuck with click buttons that match the right-handed version. I am able to toggle between the left- and right-handed modes, but the control never follows.

I don’t see a “save” button to force the left-handed mode into the mouse. Exporting the profile only creates a save file for a folder.

What am I missing?

There’s no save, because all settings should be saved instantly.

Also it’s an old unsupported version of Synapse, and I’m afraid not fully compatible with the newer OS (maybe it’s overriden on the OS level).

If you’re on Windows 11 for eg. go to settings → Bluetooth and devices → Mouse - there will be setting to change (swap) buttons on the OS level.
