What can I do if Razer Synapse is not opening?

Double-click the Mice and other pointing devices, Keyboards and Human Interface Devices categories on the Device Manager window.

2. Don’t install Razer Surround with Synapse

Enter appwiz.cpl in Run’s text box, and click OK to open the window shown directly below.

Select Razer Surround, and click Uninstall to remove it from Windows.

In case the software can’t start because Razer Central Service is missing, reinstalling the software should be able to help you.

Also, download Razer Synapse from the official website and make sure that you select the latest version in order to avoid any compatibility issues.

3. Install the latest Microsoft .NET Framework

NET Framework is a system requirement for Razer Synapse, and if NET Framework isn’t installed, Razer Synapse 3 might not be opening.

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

If an older .NET Framework version is already installed, you might need to install the latest .NET Framework for Synapse 3.0.

Download the setup wizard for the latest .NET Framework version. Then you can open the installer to add the latest .NET Framework to Windows.

4. Turn off third-party antivirus/ Windows Defender Firewall

Enter firewall.cpl in Run, and press the OK button. That will open the Windows Defender Firewall Control Panel applet.

Click Turn Windows Defender Firewall on or off.

Third-party antivirus software and the Windows Defender Firewall can also cause Razer Synapse freezing and other issues. So turning third-party antivirus utilities and the Windows Defender Firewall off might also fix Razer Synapse.

You can temporarily disable most third-party antivirus utilities by selecting disable options on their system tray icon context menus. Follow the guidelines above to turn off the Windows Defender Firewall.

Alternatively, you can consider using an antivirus with firewall to avoid these types of issues.

5. Close Razer processes

Right-click the Taskbar, and select Task Manager.

Then select any Razer processes listed under background processes, and click End task to close them.

Some Synapse users have confirmed that closing Razer processes before opening Synapse 3.0 can help if Razer Synapse is not working. To do that, just follow the above steps.

6. Check for Windows Updates

Enter the keyword update in Cortana’s search box. Then click Check for updates.

There you can press the Check for updates button to see if there are any available updates.

Windows updates might also help if Razer Synapse won’t open. The updates are usually automatic unless you’ve adjusted Windows Update settings, but you might still miss a few.
