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.
