Hi there! Does an error message pop up? If so, can you send over a screenshot of it to me through PM? I'll assist you from there.

No error message or log pops up when the application opens. This is the same for all games associated with the chroma lighting integration. *edit: I get a basic "Failed to start" screen with RETRY or LEARN MORE where retrying does nothing.

Thanks for the reply. Please send me a PM. Let's continue there.

Is there an update on this? I am having the exact same problem. Thanks!

Thanks, I've just sent you a PM as reinstalling it has made it worse... :-(

I also am having this exact issue on 2019 blade stealth, I have found that it’s only happening if my kraken TE is plugged in, if I unplug it, I can get into synapse 3 and it recognizes my blade however if I plug in the headset again it does not detect it in synapse, if I close and reopen then it does the whole failure to start. This started happening about 3 days ago, and I have reinstalled synapse a few times both with and without the kraken connected first, I have also done a fresh install of windows 10 (1903) both with and without it connected first. It seems like it coincides with synapse changing from seeing it as a headset to seeing it as a usb thx device maybe?

Hi there! Please send over the serial number of your Blade and Kraken TE to me through PM. Include the version number of Synapse as well.

well, I went to get the synapse version and decided to check for updates today, and now its at synapse version v3.4.711.71718, and it so far has opening just fine since reboot.

Recently I have noticed some of my volume macros on my chroma v2 were not working. Upon investigation I noticed that I could not even open synapse. This also seemed to effect all games that I had custom lighting for on synapse such as Overwatch and A Hat In Time, as I could not open them at all. (Instantly crashed) I have tried to uninstall razer completely and re download synapse but I still get the same error. My OS is also up to date, so im not sure what the issue could be now.

Trial and Error process I went through to finally get Synapse 3 reinstalled and working correctly: My Razer Synapse 3 stopped working so I uninstalled it and deleted everything Razer on my computer’s files. I then went online to Razer’s website and downloaded the Razer Synapse 3 install file and tried to install it. Every time I would get stopped at 2% and it would say error code 528040. I then redeleted everything Razer and even uninstalled all drivers for my Razer products (Mamba Tournament Edition, Blackwidow V2, Seiren Elite Pro, Firefly). I then rebooted my PC and left my Razer products unplugged and tried to install again and it still would get stuck at 2%. I repeated the last process but rather than installing from Razer’s website, I plugged in my Razer products and let it install Synapse 3 through their own process. It did install Synapse 3, Cortex, and Softminer. But, now each of these programs did not start. They would open and then say failed to start. I repeated both processes I did for installing twice and nothing had changed. So, I had all three programs installed but they always would say “fail to start.” I then tried repairing the applications and it did get some things to work. It kept getting an error when trying to repair Synapse 3 and when trying to open Synapse 3, but Razer Central, Cortex, and Softminer were all running normally. So at this point, I just couldn’t get Synapse 3 to install correctly, repair correctly, or open at all. in Razer Central, I hit check for updates and it said all three applications were up to date. I then unplugged all my Razer products and tried to open Synapse and nothing happened. I tried to repair it with them unplugged and it would only make it to 10% before hitting an error in repairing. I rebooted with them unplugged and tried these two things again and no success. I then uninstalled just synapse through the modify option in the uninstaller and then used razer central to reinstall and update it and it finally worked!
