I had unistalled and installed Synapse 2 more times than I care to admit. I have a tested the headset on a Windows 8 laptop and it works fine.
I have tried the following and still dead:
Kindly uninstall Razer Synapse from your PC and delete all files in C:\\Program Files (x86)\\Razer and C:\\ProgramData\\Razer directories. These folders may be hidden by default, so please be sure to unhide them. We want to ensure that there are no residual files remaining that may corrupt your installation. This is important so please do so. Restart your computer afterward.
2. Go into device manager, go to Keyboards/Audio inputs and outputs/Mouse and other pointing devices, uninstall HID Keyboard/Mouse Drivers and all other Razer product drivers, and restart your PC. Be sure to select delete drivers as well when uninstalling. Restart your computer again.
3. Turn off all Firewall and Anti-virus software to prevent any conflicts. Download and install the latest version of Microsoft .NET Framework (4.5 or higher) at http://www.microsoft.com/en-us/download/details.aspx?id=30653 (In some cases, you may need to uninstall the older version on your system). Restart your computer again.
4. Install the latest version of Razer Synapse that can be downloaded from the link below, and restart your computer again.
Has anyone been able to get their SWTOR headset working since they upgraded to Windows 10?
