Fix Razer Synapse Not Opening

Razer Synapse won't open? Here are 5 ways you can fix that

Razer is a renowned gaming-oriented company that manufactures gaming-grade PC peripherals. The company also has configuration software called Razer Synapse that provides its users with an easy way to rebind controls, configure macros to Razer's peripherals, such as keyboards, mice, controllers, and headsets. Unfortunately, sometimes users run into problems with Razer Synapse 3 failing to open on Windows 10, preventing them from configuring their peripheral devices. This article is dedicated to helping you fix this issue.

Razer Synapse is the cloud-based unified configuration software that allows users to configure and customize their Razer peripheral devices, including Razer gaming keyboards, mice, headsets, and other devices. Razer Synapse 3 is a useful tool that grants users advanced options and granular controls, allowing them to rebind buttons, assign macros, configure mouse DPI, personalize device lighting, and more.

Razer Synapse saves all of your settings to the cloud, which allows you to use your peripherals on any other computer when you log in to your Razer Synapse account.

Fix Razer Synapse Failing to Open

Razer Synapse works fine right after installing it for many users, but the next time they try to log in to their account and the software starts syncing their settings, the application fails to open and doesn't function.

In most cases, Razer Synapse starts automatically when the computer boots up. The program opens the login window, but upon logging in, it closes. The program continues running in the background, which can be seen in Task Manager, but users can't open its user interface.

Razer Synapse isn't required for Razer's devices to work. However, not having the software on your machine limits the configuration and customization options available to you. Therefore, to take advantage of all the functions Razer's devices offer, it's recommended to have Synapse installed on your machine.

So what causes Razer Synapse to fail to open? It's a difficult question to answer. This issue has been around for years and goes back to the days of Razer Synapse 2. According to many users, Razer tech/customer support is mostly useless as far as this particular issue is concerned, so no one can answer where this problem comes from or how to fix it.

Nevertheless, there are ways you may fix the Razer Synapse failing to open. There are many generic and some specific, more advanced solutions to this problem, but there are no guarantees that they'll work.

One of the ways you may fix Razer Synapse not responding or not working on your PC is by completely removing it from your PC and then reinstalling it. Some users have managed to resolve the issue by running the software as an administrator.

Others solved the issue by creating a new Razer Synapse user account. The new account won't sync any settings, so it won't get caught up with any issues. Yet other users have managed to fix the issue by manually deleting Razer folders from Program Files and Program Data.

On a side note, if you're having a similar issue with the legacy Razer Synapse 2, then try reinstalling the program, and when prompted to install Synapse Surround, click Cancel to prevent it from installing.
