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

Hello guys,

 

I’m having trouble installing my Synapse. I’ve formatted my PC today with the same ISO as before (it’s a Windows 11 LTSC) and I've updated all the drivers.

 

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
  • https://mysupport.razer.com/app/answers/detail/a_id/5996/

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 ​@guiguidalim,

Please bear with me for a bit. Can you send me a PM with your location/country so I can check for any alerts and use it when I forward your case to our Technical Team so they can further check on the installation issue?
