I upgraded to the Naga Pro V3, which prompted me to uninstall Synapse 3 and Install Synapse 4. After doing so, I am met with Installation Failed. It seems this is a common error looking at the forums, but all solutions I have found were brought to PMs so I cant actually see what was done to solve it.

​Hey there, ​@Bazkoth 

I understand that you uninstalled Razer Synapse 3 and installed Razer Synapse 4, but the installation keeps failing. 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. Looking forward to your reply.
