Why isn't my Razer Synapse 4 working after the October 28th update?

I haven't been able to access Synapse 4 since that day. I keep getting an "Installation Failed" error. I've tried reinstalling, repairing, doing a clean uninstall, removing all the drivers and reinstalling them, but nothing seems to work! I'm using a DeathAdder mouse.

Hey there, ​@geoMaximumBlueinsider670 
 

I understand that you are experiencing an "Installation Failed" error with Razer Synapse. Could you please confirm if you've already tried the following?

 

1. Downloading the Razer Synapse installer using a different web browser (e.g., Chrome, Edge, Firefox).

2. Using a different internet connection, such as a mobile hotspot or another network, to determine whether the download or installation issue is network-related.

3. Running the installer as Administrator.

4. Temporarily disabling any VPN, antivirus, or firewall software during the installation process.

 

Please let me know the results of these steps via PM so I can assist you further. Thank you!
