Razer Synapse 4 installation failure after login (Gets stuck downloading 235kb file)

Hello guys,

I’m having trouble installing my Synapse.

I installed Synapse, but right after I log in, it starts to download a 235kb file for a few minutes and then returns a message saying "installation failed". I’ve been trying to solve this problem for hours now.

What I’ve tried:

https://insider.razer.com/razer-support-45/razer-synapse-4-installation-issue-90450

I’ve also tried the cleanup tool, tried to download Synapse from Chocolatey, and I even formatted the PC again, but nothing seems to work. I also tried to create some folders manually, but with no success so far.

Do you have any insights for this? I would appreciate it a lot.

​Hey there, ​@Nito_BR 

 

Thank you for sharing your concern here. 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.
