If nothing works for you like me to start the Razer Synapse 3, I have the solution, follow the steps

1. Uninstall Razer Synapse 3

2. clean your pc well so that nothing remains Razer Synapse 3

3. After you do the previous steps, download the first version of Razer Synapse 3. (The first version is very important)

4. Install normally on your PC when you install you will see that you can already register. but they will not be able to enter Razer Synapse because the process will not start (don't worry about it, it's normal)

5. Update Razer Synapse to the latest version. When updating it won't start either. but the important thing is that they already started a session with razer central

6. last step go control panel. and they go to where the programs are uninstalled, they choose Razer Synapse 3 but this time they do not uninstall it, this time they are going to install all the Razer Synapse modules. Once installed, they will be able to appreciate that the Razer Synapse 3 already works for them. Any questions write to me. I help you
