Here are command lines to launch Synapse 4 and other windows. Handy if you want to make macros that can open Synapse 4 windows.
Applies to Synapse version 4.0.433 (the latest version). Note that settings may not display you current version correctly, it doesn’t for me.
Open Synapse 4 window:
"C:\Program Files\Razer\RazerAppEngine\app-4.0.433\RazerAppEngine.exe" --url-params=apps=synapse
Open Chroma window:
"C:\Program Files\Razer\RazerAppEngine\app-4.0.433\RazerAppEngine.exe" --url-params=apps=chroma-app
Open Quick Launch:
"C:\Program Files\Razer\RazerAppEngine\app-4.0.433\RazerAppEngine.exe" --url-params=apps=systray-left
Open Settings window:
"C:\Program Files\Razer\RazerAppEngine\app-4.0.433\RazerAppEngine.exe" --url-params=apps=razer-settings
