Razer Synapse 4

I have Synapse 4 installed for my DeathAdder Elite mouse. When I tried to use the program today, an update began, but it got stuck at 0/235 KB, followed immediately by a notification that the installation failed. This is preventing me from using the program. 

I’m here simply to advocate for Linux support. I have 3 Razer devices, headphones, keyboard and mouse and they struggle to work with Linux. Us Linux users should not have to settle for third part software like OpenRazer. While I respect their work it should not be on them to have to make these tools. We paid money for our devices, we expect support on Linux. 

i already connected it once and its not showing anymore and when i look at my razer profile it shows that it is connect and it wont let me connect it to my chroma 

Hello Razer Support Team,I am using Razer Synapse 4 with an ASUS PRIME X870-P WIFI motherboard (Windows PC), linked through the Chroma Control plugin. My Razer devices include a Viper V3 Pro, Huntsman V3 Pro, Seiren V3 Chroma, Kiyo X, and an Aether Monitor Light Bar.I have two questions.1. Which motherboard brands/models have officially supported and fully working RGB integration with Synapse 4 (Chroma Connect / Chroma Apps)? Is there an official partner compatibility list for Synapse 4? I am considering MSI (Mystic Light) and Gigabyte (RGB Fusion), and I would like to know whether either has official, stable support, including Chroma Studio, Chroma Visualizer, Axon, and game integrations such as PUBG.2. On my current setup, Chroma Studio works, but Axon, Chroma Visualizer, and game integrations are intermittent, and sometimes only the motherboard responds. The integration works normally when the Aether Monitor Light Bar is turned off. If the light bar powers on during a cold boot, the

Dock firmware 1.0.14.0, Synapse version 4.0. [removed by moderator] ."When I switch mouse profiles via the Razer Mouse Dock V2 Pro, only the button functions change, while the LED lighting does not update. In the Synapse 4 software, the profile for the Basilisk V4 Pro does not change at all."Please let me know if there is any way to fix this issue. Thank you!

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

Synapse for Windows V4.0.86.2610200951 / Windows 11 / Razer Tartarus V2Lots of us have reported macros showing numbers like "49", "50" or "71"instead of key names. I think I found the cause. It is the import path,and it is reproducible in about two minutes on any device.MINIMAL REPRO1. Create a new macro in Synapse 4 (any keys). The editor shows key names.2. Export it to XML.3. Delete that macro.4. Import the file you just exported.5. The editor now shows raw numbers instead of key names.Same macro, same file, one round trip.WHAT IMPORT CHANGESExport the macro again after step 4 and diff it against the file fromstep 2. One key event, before and after:  BEFORE (created in Synapse 4)        AFTER (re-exported post-import)  <MacroEvent>                         <MacroEvent>    <Type>1</Type>                       <Type>1</Type>    <Id>1792666983228</Id>               <Id>1</Id>    <KeyEvent>                           <Key

There’s an available module in my Razer Synapse 4 installation called “Exchange”, but I can’t install it or figure out what it does or what it’s for. Is this a bug?

 I love my Razer Wolverine — the build quality, features, and precision are excellent. In most modern games I’m almost as accurate with it as I am with a mouse.That said, the lack of an Anti-Deadzone option in the software is a real limitation. It forces players like me to look at competitors when playing older titles that don’t have native deadzone adjustment — especially on consoles .An Anti-Deadzone feature would be a huge quality-of-life improvement and would make the Wolverine even more competitive across a wider range of games. Many of us would really appreciate seeing this added.Thanks for considering it!

Hi Razer, I recently bought your wolverine v3 TE 8k, i love this controller a lot, but i find the software very limited. I used to be able to apply anti-dead zone settings to my controller to counter the fairly high dead zone in older games, as well as customize the aiming curve using Bézier curves, for example. Unfortunately, your software doesn't offer all these options, including the ability to adjust the dead zone more precisely, in increments of 1 instead of 3, as was possible with the Vader 5 Pro software. I think implementing this in your software would greatly improve its quality and credibility with many gamers. It would also offer a complete controller experience (which is excellent) that I unfortunately find somewhat hampered by the software, or at least not used to its full potential.Thank you for your attention !! 

Bonjour à tous,Depuis la mise à jour vers Razer Synapse 4, mon Tartarus V2 ne fonctionne plus comme avant. Toutes mes attributions de touches affichent le message « Cette attribution de touche nécessite Razer Synapse », et mes macros et raccourcis ne répondent plus.Le paradoxe : Synapse est bien installé et lancé, c’est justement la mise à jour qui a cassé le fonctionnement. Un périphérique à plus de 80 € qui devient inutilisable après une mise à jour logicielle, c’est inacceptable. Et aucune solution de repli n’est proposée : impossible de revenir à Synapse 3.@Razer, pouvez-vous nous dire :si ce bug est connu et corrigé prochainement ? s’il existe un moyen officiel de revenir à Synapse 3 ou de récupérer mes profils ?Si d’autres ont le même problème, ou mieux, une solution, je suis preneur. Pour l’instant, mon Tartarus V2 sert de presse-papier. Et ca fait cher le presse-papier!!

As of 10/20/2026 Razer Synapse 4 non-beta (4.0.86.2610120714) causes a double typing problem when synapse is open on the Huntsman V3 Pro 8KHz fullsize, tkl, and the new mini, not the 65% HE (unsure about tkl HE, and non pro tkl). Beta vertsion of Synapse 4 works fine with tkl and fullsize but new mini still has the problem.When the WASD and QE keys are assigned to gamepad controls and passthrough is enabled those keys double type characters.Temproray solution: disable hypershift (fn) on gamepad assigned keys and double typing goes away, however Fn+WASD QE will no longer type those letters, not that anyone really cares… By default Fn + any key functions as if that key was pressed (F types F and fn + F types F), except the ones that light up white and have pre-programmed secondary functions at firmware level (J types J and fn + J is page up on Huntsman V3 Pro mini).For some reason Synapse 4 thinks Fn key is pressed when passthrough fuctionality is enabled, causing the keys to double type

After updating to the new version my synapse cannot detect wuwa on my blade 16 anymore. Even after trying manually adding the game to linked games tab, it won’t show. I tried fix synapse, re-download it, restart my blade 16, deleting and re-download wuwa, and none of it works. Also Razer Cortex doesn’t detect it. But the strange thing is when I manually add wuwa to cortex it pops up “game already installed” thing but it doesn’t actually show in the installed game tab.

Hi, i am unable to disable auto-updates. In the old razer snypase, there was a setting for me to disable this, however, in this new razer synapse 4, I am unable to do so. When I open the settings, there is no option for me to disable auto updates. I have attached a screenshot below  

Whilst the re-mapping of the thumbstick by Razer has been a wonderul and welcomed update, there is still an issue that needs to be addressedWith the thumbstick mapped to movement (left controller stick), if you engage the thumbstick whilst also looking around with the mouse the game flips between console controls and pc controls.The only real time this seems to have a negative impact is when trying to perform an action that relies on the mouse button being held down for a long period to carry out the action e.g. switching to med kit and then holding mouse fire button to heal OR switching to grenade and holding the mouse fire button to aim and then throw the grenade. Moving and looking around during this operation seems to reset the action, as I believe the controls are switching from PC to console. In the case of grenades, it throws the grenade before you’ve released the fire button.I have found a work around which is to bind console right trigger to a Tartarus button. Pressing this co

I’m on the latest version of Synapse 4, Windows 11, fresh hardware and software install.Blackwidow v4 Pro, Basilisk v4 Pro, Wireless Charger v2, Firefly v2, Laptop Cooler, fresh out of the box and on updated firmware.Windows 11, 25H2 fully up-to-date. The only way I can get Global Shortcuts working properly is to restart Windows. Prior to a restart, they work sometimes and not others, with no consistency or common variables. A quick Google search reveals this problem going back for YEARS across multiple platforms. The other thing that comes up a lot on those searches is the inability to set a lock-screen or pre-login profile for Razer hardware. The answer is usually, “But you need a profile to load, which needs Synapse, which needs a user, so therefore it’s never happening.” Other vendors don’t have a problem making this work... The common thread I immediately draw between these two seemingly disparate problems is that both would require a program to run in SYSTEM context. There’s evid

Hi Razer team and fellow Kraken V4 Pro owners,THE PROBLEMSensa HD Haptics on the Kraken V4 Pro is a single global setting. It is not saved per profile, so it stays on all the time: music, YouTube, calls, notifications - everything vibrates and the battery drains fast. This was already reported a year ago ("kraken v4 pro/synapse 4 -- haptics setting not saved per profile"), but that thread was locked and moved to PM, with no public fix.Razer's own spec shows how much this matters: up to 50 h with haptics and lighting OFF vs. up to 13 h with haptics and lighting ON (2.4 GHz). Most of us only want haptics while gaming.WHAT I'D LIKE TO SEE (either option is fine)1. Save haptics on/off and intensity per profile (like EQ and other audio settings), so the game-linked profile can have haptics and the default profile can have them off.2. Or, a simpler toggle: "Enable haptics only while a game is running/in focus".WHY THIS SHOULD BE EASY - THE BUILDING BLOCKS ARE ALREADY IN SYNAPSEI looked at th

I have a Razer Tartarus V2 and I have been using the keymapping feature of Razer Synapse for quite some time now. However due to the recent updates to Synapse 4, it no longer works. I am given the message “mappings require razer synapse” and hence no longer works.Edit: Upon further tinkering, it seems as if its just the D-Pad that just doesn’t work anymore? 

Bom dia Instalei o Synapse, mas logo depois de o fazer login, ele começa a baixar um arquivo de 235 KB por um tempo e depois exibe uma mensagem dizendo "falha na instalação". Estou tentando resolver esse problema desde segunda-feira  Meu Notebook está com Windows atualizado, drivers também, até tentei a ferramenta de remoção de driver razer e reinstalar de novo, não está baixando de jeito nenhum, baixei no meu computador também e fica a mesma coisa

Hello, good morning! I use two Razer products: a Tartarus V2 keypad and a wireless Naga V2 mouse.I had to restore my PC, and now Razer Synapse won't install.The executable installs, but when I try to open the program, the startup bar appears and it fails to load. It might be a corrupted link, as I tried installing it on another laptop I own and encountered the same error.Without Synapse, I cannot configure either peripheral.I look forward to your reply.

Hello guys,I’m having trouble installing my Synapse. I’ve formatted my PC today with the same ISO as before (it’s a Windows 11 LTSC) and I've updated all the drivers.I installed Synapse, but right after I log in, it starts to download a 235kb file for a few minutes and then returns a message saying "installation failed". I’ve been trying to solve this problem for hours now.What I’ve tried:https://insider.razer.com/razer-synapse-4-55/i-can-t-install-razer-synapse-87352 https://insider.razer.com/razer-support-45/razer-synapse-4-installation-issue-90450 https://mysupport.razer.com/app/answers/detail/a_id/5996/ I’ve also tried the cleanup tool, tried to download Synapse from Chocolatey, and I even formatted the PC again, but nothing seems to work. I also tried to create some folders manually, but with no success so far.Do you have any insights for this? I would appreciate it a lot.

Hardware: BlackWidow V4 Low-profile HyperSpeed (keyboard firmware 1.4), HyperSpeed dongle(USB PID 0x02C9), Basilisk V3 (PID 0x0099). Windows 11 Home 26200.Software: Synapse 4 stable 4.0.827, proxy RzChromaSDKProxy_v1.2.3.2.Issue: in wireless (HyperSpeed) mode, Chroma SDK applications cannot light the keyboard.lighting-engine.log shows the keyboard registered as the wired product id with no handle:  addDevicesToChromaStudioEngine() productId:716 ... device handle:undefinedIn wired mode the same line reads "productId:716 ... device handle:3" and everything works.Synapse also shows no keyboard lighting tab in wireless mode. SDK calls still returnresult:0, so applications cannot detect the failure.The hardware path is fine: raw Razer HID commands sent through the dongle (transactionid 0x9F) are accepted and displayed by the keyboard, both custom frames and built-in effects.So the issue looks like a Synapse-side mapping of the dongle (0x02C9) to the wiredproduct (0x02CC / 716).Related: the

Now can switch ANC on/off or ambient, but cannot adjust ANC level in Synapse 4 version 4.0.86.2601160905 and beta version 4.0.86.2511170410.Synapse 3 and Audio app are correctly. Since 02-Nov-2024, I reported this issue to Razer Support staff.By the way, last month (10-Dec-2025) Razer Support staff replied me that they tried to fixed.What are Razer doing?
