How to Fix Razer Synapse Not Opening

Razer Synapse provides users with an easy way to rebind controls and configure macros to Razer's peripherals, such as keyboards, mice, controllers, and headsets. Unfortunately, sometimes Razer Synapse 3 won't open for some users. This article is dedicated to helping you fix this issue.

For many users, Razer Synapse works fine right after installing, but the next time they log in to their account and the software starts syncing their settings, Synapse fails to start.

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.

How to Fix This Issue?

One of the ways you may fix Synapse not opening 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.
