So it seems, Synapse 2 just cannot open in Windows 11. I've tried everything, reinstalling, changing DPI & compatibility settings. I can't get it to open the window and even login. It shows up in the task bar overflow and refuses to open. It's the only app i'm having trouble with so far, in Windows 11

To reiterate: I'm using Razer Synapse 2 for my legacy devices, Razer Anansi Keyboard and Naga 2014 mouse. After upgrading to Windows 11, I can't even get Synapse 2's window to open up and login. I've tried reinstalling and many compatibility modes. Am I shit out of luck?

UPDATE:

was about to reply to some of you with angry comments for spreading misinfo because i contacted Razer and they assured me they're not updating legacy software for Windows 11.

Then i tried it again, and again, and finally, i figured it out. This definitely didn't work on the early versions of Windows 11 but it appears to have changed. I reinstalled Synapse 2 legacy as someone in the comments did, but that wasn't enough. I'm on the latest version of W11.

I tinkered around and changed the High DPI scaling override-
located in the Compatibility Tab of RzSynapse.exe Properties.
Make sure the Override Box is checked,
click the dropdown menu and switch to "Application."
Mine was initially set to System Enhanced.

Yours may have worked without a flaw because it was already set to Application for DPI Override.

This was my initial theory to get it working again when first installing Windows 11 but no change of DPI worked then nor any compatibility setting. Things have finally changed!

Hope this helps anyone else struggling

Hiya,

first off: yes, I did contact Razer Support and it was infuirating and not helpful. They just said Synapse 2.0 & Win11 don't go together - despite the fact it's been working for years. Until a couple of weeks ago.

The issue is, I can open Synapse 2.0 and if I want search for updates, but I can no longer access the settings for my keyboard (Deathstalker). None of the function keys work anymore, no chroma fancyness, nothing. Opening Synapse as admin or compability mode don't work either.

Does anyone have the same problem and found a workaround? If it's broken forever, I'll live with it but I just wanted to check if there's a slither of hope xD

Thanks in advance!

TL;DR: If you're unable to reinstall Razer Synapse after an uninstall, try using Chocolatey package manager. It successfully installed Synapse when the standard installer and other methods failed.

Hey r/razer community,

I recently faced a challenging issue where, after uninstalling Razer Synapse, I was unable to reinstall it using the standard installer. The process would start but then abruptly close without any error message or indication of what went wrong. I tried several troubleshooting steps, including cleaning leftover files and registry entries, running the installer as an administrator, and performing a clean boot, but none of these resolved the issue.

Here's what I did to finally get Razer Synapse reinstalled on my Windows machine:

1. Manual Cleanup: I started by manually removing all Razer-related files and folders from my system, including:

   • C:\ProgramData\Razer

   • C:\Program Files (x86)\Razer

   • C:\Users\[YourUserName]\AppData\Local\Razer

   • C:\Users\[YourUserName]\AppData\Roaming\Razer

2. Registry Cleanup: After backing up my registry, I removed entries related to Razer from the following paths (please be very careful with registry edits and ensure you have a full backup before making any changes):

   • Computer\HKEY_CURRENT_USER\Software\Razer

   • Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Razer

   • Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

   • Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

3. Using Chocolatey: When all else failed, I turned to the Chocolatey package manager. Installing Synapse through Chocolatey did the trick when the standard installer didn't work. The command I used was:

   • choco install razer-synapse-3 1.16.0.543 -y

Surprisingly, even though Chocolatey reported that only 1 of 2 packages was installed successfully, Razer Synapse appeared in my list of installed applications. I was then able to open it and update it via Razer Central.

Additional Info:

• Even if you're installing Synapse for the first time and running into issues, Chocolatey might help.

• You might want to try installing via Chocolatey right off the bat, skipping the file and Registry deletion steps, as it seems to handle installation issues more gracefully.

Just an FYI for anyone who might be having similar issues - hopefully, it saves you some time and headaches!

Cheers!
