Hi , AleyCool.
I am Ivan, I will help you with this.
Make sure net framework version 2.0 and 3.5 is active in the control panel then uninstall raze synapse using Revo uninstaller to delete registry and temporary application files.
Reinstall Razer synapse and install Net framework 4.8 from the link below.
