Razer Synapse 4

Blackwidow V4 Pro and Synapse 4 installed.If Synapse is running and I run other certain apps, like a music streaming app, multimedia keys don’t work there and volume control stops working. As soon as I exit the music streaming app, volume control shows up reacting to the roll bar with significant delay. But sometimes it stops working at all. Only if I exit Synapse, it’ll be working.I tried all the steps proposed by support documentation, like rei-installation of the keyboard driver, Windows update and clean re-installation of Synapse, but they didn’t work.

someday i installed razer synapse 4. it was perfectly working for over a half year. one day my hedephones razer blackshark v2 didnt connect to the pc(they were working but i couldnt change setting). after some time synapse stoppped opening. i delete all files connected to the razer and set my pc to factory setting(with all my files). i reinstalled synapse and it still doesnt open. i did all things from guide on youtube and it didnt help. my website version of synapse also doesnt see my devices(basilisk v3 and blackshark hyperspeed v2)

Everytime I press the mute button on my headset, my mic volume drops to 0.I’ve seen that a lot of people have this issue and although I tried everything to fix this problem, there is no solution yet so I’m waiting for Razer to correct it…

Hello. I constantly face an issue where "RazerAppEngine Window" process prevents my PC from shutting down normally. Sometimes an additional error window pops up during this.When will this be fixed? All of this happens on new PC with a clean Windows installation. It has been more than 1 year since first post about this, but bug is still not fixed.Existing threads discussing this issue:https://insider.razer.com/razer-support-45/razerappenginie-exe-is-preventing-shutdown-74690https://insider.razer.com/razer-support-45/razerappengine-exe-prevent-windows-shutdown-76967https://insider.razer.com/razer-support-45/please-fix-synapse-4-bug-causing-computer-shutdown-issues-68815 Additionally, while looking into this problem, I noticed extremely poor RAM optimization. The RazerAppEngine process takes 0.25 GB in background, grows to 1 GB if I open the app window, and stays at 0.5 GB after closing window. And this is not counting other Razer background processes.It feels like software optimization w

Hello,I recently purchased a Razer Wolverine V3 Pro, and I am currently unable to use it properly due to a critical issue with Razer Synapse.The controller is detected, but Synapse is stuck on "Loading" / "Syncing Profiles", and no changes are applied to the device at all. This makes core features like remapping, RGB, and stick calibration completely unusable.Key Issues:No settings are saved or applied to the controller RGB lighting does not change Button remapping does not work Stick calibration and deadzone adjustments do nothing Synapse remains stuck syncing indefinitelyMajor Concern:The required Synapse services are missing entirely from the system:Razer Synapse Service (missing) Razer Central Service (missing)Only the following services exist:Razer Elevation Service Razer Game Manager Service 3This indicates that Synapse is not installing or registering its core services correctly.Troubleshooting already completed:I have already performed extensive troubleshooting, including:Multi

Dear Razer Support Team,I am experiencing an issue with my Razer BlackShark V3 Pro headset microphone.Details of the problem:  - When Razer Synapse is uninstalled, the microphone works normally.  - Once Synapse is reinstalled, the microphone stops working completely.  - I have already updated both the headset and dongle firmware to the latest versions.  - The device is recognized by Windows, but the microphone input remains at zero.  Could you please advise on further troubleshooting steps or provide a patch to resolve this issue? I am happy to share logs or perform additional diagnostics if needed.Thank you for your assistance. 

Just bought a new Barracuda Pro headset and a Viper V3 HyperSpeed mouse. Whenever I launch installer for Synapse, I get Server Access Unavailable. Went through all of the troubleshooting steps found online with no luck. Tried to updated BIOS, turn VPN on/off, turn Firewall & Windows defender ON / OFF,  add exceptions etc to firewall, change IPV4/IPV6 settings,  launching installer through earlier versions, trying to install other razer apps first (can’t install anything, same error every time), made sure network drivers and windows is updated, tried wired connection, tried mobile hotspot, WIFI, removed all razer devices and their drivers. Probably forgot to mention a few more since I’ve been at it for hours.Literally nothing seems to make a difference and at this point I’m losing hope which is a shame since there’s so much of the headset features locked behind Synapse and I just bought them today. Any help would be greatly appreciated!

Razer Synapse 4 just randomly crashed on my PC a few days ago, and since then, no matter how many times i reinstall it, it crashes on launch every time, and i think it is because it doesn't have the services that it needs to work. It only ever installs the Razer Elevation Service, and I think it cant install them because it can't get the services package from assets.razer.com, or something. It also just doesn't install the C:\Program Files (x86)\Razer\Razer Services\ folder on my PC. Does anyone having a working synapse 4 installation and has this folder so i can install it through cmd or powershell? Maybe through google drive or something. 

Since the update V4.0.86.2605190956 of Razer Synapse on Windows, the button 9 of the Razer Naga V2 Pro mouse cannot be modified at all. Here’s what button 8 looks like, what is expected: And here is button 9. Notice that the turbo function simply isn’t present: Since turbo was activated prior to this update, it still works. However, this update changed something in the behavior which make the function behave extremely herratically. To fix it I had to tone down the turbo on the button 8 for scrolling up. However, due to this bug I cannot do the same for button 9. A partial fix comes in the way of closing Razer Synapse completely. Even though both of these function uses Razer Synapse, closing it seems to make it behave non-herratically as it did before. However, I change between two profile often so having to re-open Razer Synapse, change profile and close it again is not convenient at all.

I'm experiencing an issue after logging into Razer Synapse. There's an undeletable default app profile that seems permanently saved in the cloud. It syncs back to my local device every time I log in, and it sometimes prevents me from adding new profiles.

Tired of using Rawaccel every time I turn on my PC I need to open the program. I want to ask you guys when is Razer going to enable me to fix the rotation of my mouse? Or the hardware is limited and the Razer programmers will not make my Deathadder v3 Pro have mouse rotation? I already sent two feedbacks months ago and still no mouse rotation feature. I need to know so I can make up my mind to buy another mouse with mouse rotation built in.

You ruined my ability to make lighting profiles. Haptics have been a huge mess. I'm done. Can't take the abuse of the new Razer. You never finished supporting Lian Li still missing 26 Led fan option for Lian Li TL LCD 140mm fans to be used with Razer Chroma Addressable RGB controller. I asked for Tartarus on large format RGB mousepads in 2019. That has been sitting in beta working for over two months. I told you Clio has low volume. Still not able to hear anything in game from this as a rear speaker. Works with Voicemeeter. I can have actual 5.1 and volume. Haptics are very unreliable and inconsistent. Hammerhead v3 hyperspeed offers THX Spatial Audio App yet isn't supported properly. https://youtube.com/watch?v=lobJbP2ArY4&si=P7vfhEfx1JmWhUab https://youtube.com/watch?v=kxZO8lzL39M&si=Q2g2y9mo53NQ2dwM https://youtube.com/watch?v=AxcIs1gtR0k&si=YOVgjKegiRsP6lFF All these years collecting special editions and working from the Chroma ecosystem wasted. It's all too much! I

My Razer mouse indicates 2 states via LED: 1. Awaked from sleep and no Synapse detected (Spectrum Cycling LED) 2. Synapse detected and just linked teh mouse (Switched profile’s color LED)Issue: My Razer BASILISK V3 X HyperSpeed does totally not remember my customized DPI and every awaking from sleep reverts its DPI to default. (400/800/1600/3200/6400 DPI) Then Synapse 4 applies my customized DPI list to my mouse again but it spends about 5 secs until the DPI reapplied so it makes me goes mad.The mouse works cool but its software’s awful and completely spoiling customer experiences.Do NOT tell me to update or reinstall Razer Synapse.

Hello all,On one of my PC Synapse 4 is not starting up properly.  During the startup phase, it is downloading files but it doesn’t complete.  It downloads files non-stop reaching 50 000 % + and keep rising. I have all the latest update of Windows 11and without any razer devices connected but it is always bug at this place. Anyone encounter this and have a workaround? Thank you!

Linked Games and Auto Profile Switch no longer works after an Synapse Update (Jan 2026), profile switch doesn't affect the apps i'm using. i did a clean install to the software, the linked games now takes forever to scan games and i can't even add programs to it.

The audio equalizare in Razer synapse 4 is not doing anything to my sound, cant modify anything, the problem started 3-4 days ago. 

The problemAfter the recent Razer Synapse 4 update, somewhere around the end of April - the beginning of May, my laptop settings tab became completely blank.Exactly the same blank tab as in the image in the topic at the link:https://insider.razer.com/razer-synapse-4-55/kraken-v3-pro-tab-is-blank-70072?postid=236934#post236934Only in my case, instead of "kraken v3 pro" it was my laptop "blade 16".The solutionI managed to fix the problem this way:Delete the "Razer" folder in the directory - "C:\Users\%username%\AppData\Local\"; Open "System Settings -> Apps -> Installed apps -> Razer Synapse (three dots, click on modify)". Click "Repair" in the app that opens.The same actions can be seen in the following videos:https://youtu.be/upGhuFuAIDo?t=17, 0:17 - 0:52 https://youtu.be/v0vHE1ooHDc?t=57, 0:57 - 1:25After completing these steps, log in to your profile in Razer Synapse. It will load the previous settings from your profile and download and install all the necessary modules, jus

Synapse 4 is garbage it doesn't work half the time and the other half it keeps crashing, i have never used such a buggy software in my life, its literally reseting all my profiles to default even if i re-import them or create new ones, if i switch profiles for a differnet game its keeps jumping back and forth from 1 to the other, why this is even available yet is beyond me, cant use Synaps 3 installer "Server access unavailable" im using the Razer Tartarus V2 and its completely un-usable with Synapse 4, why could they not allow us to use Synapse 3 locally i dont understand, those that still have synapse 3 can use it locally 

I’ve seen some others have had some problems with installing Synapse 4, but the fixes either I can’t implement because they’re too technical (using PowerShell) or they don’t work for me (closing any Razer processes in Task Manager).Does anyone have any recommendations for a fix that works and isn’t technical?
