Steps on How to Fix Razer Synapse Not Opening Issue

Why is Razer Synapse Not Opening on Windows 10

Before you begin fixing the Razer Synapse not opening issue, ensure that all system requirements are met. These are as follows:

  • Windows 10 64-bit or Windows 11
  • About 500 MB of free hard disk space
  • E-mail address
  • Download software, license acceptance, and have an internet connection to activate full features and get software updates. After activation, the full feature will be available even though you aren’t connected to the internet.t.

Step 1: Reinstall Razer Synapse software

One of the most common reasons razer synapse is not opening in Windows 10 is that the software is missing key files. It can occur due to an incomplete installation procedure, files infected by a virus or other applications interfering with the installation of Razer Synapse processes. The best method to avoid this possibility is to reinstall Razer Synapse on your computer.

How do you download and install Razer Synapse software?

Before you reinstall Synapse, you should completely remove it and delete any related residual files. After that, you may need to use tools such as IObit or Geek Uninstaller. Finally, to reinstall, download Razer Synapse from the official website.

Once the download is complete, follow the steps:

  • Start the executable.
  • Before sending you to the installation window, the program will extract and arrange all essential files.
  • Before going on, you must accept the Razer end-user license.
  • The installation procedure will begin after the license has been agreed upon.
  • Wait for the installation to finish before clicking the Finish button to leave the installation wizard.

After you reinstalled Razer Synapse, open it up again to check if the problem has been fixed. If not, move on to the next step.

Step 2: Reinstall the Razer device drivers

If there is an issue with the Razer device driver, the program may fail to start. As a result, you should also reinstall the device drivers. The following are the steps for reinstalling Razer device drivers:

Start by searching for device management in your Windows search box. Then, extend the following; keywords, mice and other pointing devices and human interface devices categories.

  • Right-click on any Razer devices listed in these categories and choose to uninstall the device from the context menu.
  • On the uninstall dialog box, you may see the option “Delete the driver software for this device.” Ensure to check it if it occurs.
  • Then select uninstall.

Unplug all Razer components from your system and restart the computer. After restarting, reconnect all Razer peripherals to the system. Windows will recognize the Razer components and begin downloading the necessary drivers. You may also do it manually using Windows Update and Device Manager.

When Windows is done installing the necessary drivers, test your Razer Synapse to see whether it opens properly. If the problem persists, follow the instructions below.

Step 3: Uninstall Razer surround

Razer Synapse will display a feature update window when connecting your PC to the internet. In addition, the popup recommends installing Razer surround. However, installing Razer Surround on your PC may cause issues with Synapse and result in the Razer Synapse not opening issue. As a result, you should avoid installing Razer surround and uncheck the recommendation.

If you already have Razer Surround installed on your computer, remove it.

  • You can search for “Add or remove programs” or open the RUN dialogue box and type “appwiz.cpl” to see the list of installed programs on your PC.
  • Locate and choose Razer surround, then click on uninstall to remove it from your computer’s operating system.
  • After uninstalling Razer surround, test your Synapse software again and see if it helps.

If Razer surround does not appear in the list of installed apps, skip this step.

Step 4: Delete any temporary files related to Razer Synapse.

Programs for individual use generate temporary files. These files may remain in your system even after the application has been uninstalled. Besides, the files might cause problems with the program’s functions in the future; therefore, it is good to remove them from time to time. Follow these steps to remove temporary files using the RUN command box;

  • Open the RUN command box, type “tempo,” and press OK.
  • You will come to the temp folder at C:UsersUserNameAppDataLocalTemp
  • To select all of the files in the Temp folder, press Ctrl + A and click Delete.

Launch your Razer Synapse program after deleting the temporary files to see whether the problem remains. If Synapse is not opening yet, go to the next step.

Step 5: Download and install the Microsoft .NET Framework.

Razer Synapse will request for installation of the Microsoft.NET framework to improve efficiency. However, besides serving as a framework of shared code .NET framework also offers an application runtime environment. It’s thus recommended that you install the most recent .NET framework on your computer. If the framework is missing, the Razer Synapse may not open.

Step 6: Deactivate your antivirus software and test Razer Synapse. 

Whether Windows Defender or third-party antivirus software can make it difficult to launch Razer Synapse, antivirus software can relocate data from their original place to their vault directory to detect anything unexpected or malicious. If your antivirus program deleted or quarantined any files in the Razer Synapse installation directory, it may prevent the application from starting.

Therefore, to turn off antivirus (if you’re using Windows Security), launch Windows Defender and navigate to virus and threat protection. Then turn off real-time protection and any other comparable settings that are accessible. Besides, in the case of other antiviruses like Norton, Kaspersky and Avast, the system tray context menu should have a quick deactivate antivirus option.

By stopping the antivirus application and then reinstalling and testing Synapse, you can determine whether the antivirus program is blocking Synapse from launching. If Razer Synapse still does not open, the problem is somewhere else, so move on to the next step.

Step 7: Turn off Windows core isolation.

When the Core isolation feature is activated, Windows uses virtualization technology to create a protected section of system memory to operate the Windows system processes and security applications. Besides, it serves as a layer of protection to safeguard the system process from virus/malware assaults. Unluckily, enabling core isolation might result in the Razer Synapse, not opening problem.

To test this:

  1. Deactivate Windows security’s core isolation feature, which can be found by going to Windows security > Device security > clicking on core isolation details > then disabling memory integrity.
  2. Try running the Razer synapse after removing “memory integrity.”
  3.  Finally, if it doesn’t work, try disabling the Windows firewall.

Step 8: Disable the Windows firewall.

The Windows Defender firewall might cause the Razer Synapse program to freeze or prevent it from starting. Therefore disabling the firewall might resolve the Razer Synapse not opening issue.

How to disable the Windows Defender firewall

  • To launch the RUN dialog box by pressing Windows + R.
  • In the Run dialog box, type firewall.cpl and press OK.
  • The Windows firewall window will open; click on the left panel to “turn Windows Defender on or off.”
  • Confirm that the Windows Defender firewall is turned off for public and private networks.

Disabling Windows Defender is not a great idea if you stay connected to the internet. Besides, this step is intended for Synapse application debugging, not startup issues. So, whether it works or not, you should reactivate Windows Defender.

Step 9: Turn off the Razer background process 

It makes sense to force-stop the Razer background process before opening Razer Synapse on Windows 10. A running background process might sometimes prevent another instance of the same software from launching; thus, shutting them down will help.

How to turn off the Razer background process

  • To access the task manager, use ctrl + shift + ESC.
  • Select any Razer process from the background processes area and click the end task option in the context menu.
  • After turning off Razer-related background processes, open Razer Synapse as administrator to determine if the Synapse starting fail problem is resolved.

Step 10: Look for any available Windows updates.

Why is Razer Synapse Not Opening

A Windows update may help resolve the Razer Synapse startup problem if nothing else works. Windows continues to release updates for different security upgrades and regular fixes. Usually, Windows 10 updates are automatic, but the procedure may require manual action if you modify the update setting.

How to check for windows update

  • In the Windows search bar, type “update” and click the check for updates.
  • The Windows update will display. If your Windows is outdated, click the check for updates button.
  • Download any available updates.
  • Restart your computer and relaunch the application to see whether the update resolved the Razer Synapse, not opening problem.

Razer Synapse should now open without issues on your computer; if not, we recommend restarting the PC and trying the application on another computer with a comparable operating system, if one is available.

If the application works on another PC with a different version of the operating system, it may suggest that your operating system has some compatibility difficulties with the program. At this stage, try contacting the Razer support team for assistance.
