Check if the application you are using is officially supported by Chroma Apps. Check if you are using the same Razer Synapse version for all the Chroma-enabled devices.

r/razer on Reddit: Razer Chroma stopped working all of a sudden. (Synapse 4)
January 14, 2025 -

I was going to change my computer's RGB lighting, and I open Razer Chroma and this is the screen I get:

Razer Chroma program. Clicking the 'RETRY' button attempts to reload the program but it fails. Razer Synapse program. Everything works completely fine.

I tried doing a repair, uninstalling and installing and nothing fixed the issue. Razer Synapse works just fine. I also went to the Razer support page, but there was nothing about the 'Failed to start' issue.

How can I fix this issue (without reinstalling Windows)?

I use the synapse beta and the chroma beta, and I find that my chroma apps can’t identify any software, such as audio visualizer. Cyberpunk 2077 and Overwatch 2 on my computer don't work either. Does anyone like me or know how to fix it? My device is BlackWidow V3 Mini. Thanks a lot.

Yeah, many are facing the same or similar issues as you are due to their bs software of upgrading to synapse 4. There is NO fix as Razer themselves need to seriously investigate and release a damn fix.

Sometimes the only way I have found to fix these issues is to completely uninstall Razer Synapse using "BC Uninstaller"(BullCrap Uninstaller) This will remove any leftover files from chroma, synapse, Axon, cortex, etc Using "Driver Store Explorer" to force delete all Razer and THX drivers from your pc Then using "Revo Registry Cleaner" to clear out any leftover useless Registry keys left behind by any Razer apps and drivers. IT'S HONESTLY SO FUCKING STUPID HOW MUCH EFFORT ONE HAS TO PUT IN TO GET THINGS TO WORK. You can also try going into the windows Settings > Installed apps Looking for Razer Synapse clicking on the three dots to the right. Clicking Modify/uninstall whichever one honestly. It'll open up the Razer Uninstaller. From there you can update/repair the apps. Sometimes this fixes the issue Edit: If you decide to go the long route and do a complete uninstall/cleanse as stated above; unplug any and all Razer Hardware. Use a generic mouse and keyboard if you're on a desktop. Don't plug stuff back in until you've cleaned>rebooted>installed synapse After plugging all your hardware back in and rebooting (x) amount of times from every device it ask for you to do that. Check for driver updates via Windows Update. Some devices won't work until after you grab a driver from the windows update Good luck man... Try not to punch a hole into the PC... It will be very tempting

This is suddenly happening to me as well. I just switched from Synapse 3 to Synapse 4. Chroma and visualizer were working ok and would start on PC boot with Synapse 3. After upgrading to Synapse 4 the visualizer worked for about a day or so, as I was trying to re-set up my environment and familiarize with controls and options. But around day 3 the visualizer is no longer loading. I have tried repairing all of the Razer apps. I have removed and reinstalled Synapse and Chroma and it still isn’t working correctly.Another note is after the PC boots up, when I use the Razer notification icon to pop up the display for the Razer menu where you can change profiles for each device (I’m not talking about the synapse GUI it’s the quick menu from a single click) in this menu it also shows at the bottom the Chroma settings and the Visualizer one has been starting with ‘Always Off’. Now in the first couple days where this happened, in this same menu, I just switched it to ‘Always On’ and I immediately saw the lights change to the correct Visualizer profile (instead of the Quick Effect). This is also no longer working. Now when I switch this setting to ‘Always On’ …nothing happens. Another side note - previously I was clicking in this area to open the Chroma app. Now when I click in this area, 2 different things happen - Sometimes, I can see an app start to open but then immediately disappear - other times I get a Windows dialog that says you don't have an app to open this program, go to windows store to search blah blah.To make things worse, I just got Razer Freyja and Synapse is saying ‘Launch the Chroma app to further customize...” which I cannot get to open. This issue was already happening before I connected the Freyja.Also sorry for lengthy reply but I also have several peripherals and lights setup for the gamer room, and getting quite frustrated with the amount of time and money put into this for it to just stop working without any explanation.

It was working fine as can be seen in the attachment with only Chroma Visualizer set on reactive background! Cannot get it back to this setting because I cannot enable the Visualizer on Razer Chroma. I deleted the apps, reinstalled them. The preview settings just would not work again! I want to get it back to this setting. Wave as reactive and spectrum in the background. But I just cannot 😭 HELP ME. Been at it for hours. This is super annoying.
