I’m here to share how can I troubleshooting the issue that 7.1 Surround Sound won’t launch at all.
First, thanks to peoples in this thread for solution.
In my situation, I config my windows to move Roaming folder to other drive, let’s call it E:\Roaming, to save some space and kept programs config safe.
The root cause is that, from what I understand, when install the 7.1 Surround Sound app while have roaming folder located other than C:\, the installer will install the app data both in C:\Users\<User>\AppData\Local\Razer and E:\Local\Razer, while mostly app data will be stored in C:\Users\<User>\AppData\Local\Razer.
But when try to launch the razer app, it will try to look for app data in E:\Local\Razer instead of C:\Users\<User>\AppData\Local\Razer.
To solve this, first, copy folder “RzAppEngine” inside C:\Users\<User>\AppData\Local\Razer, to another location, in this case, E:\Local\Razer, and replace everything inside.
Then remove old “RzAppEngine” folder inside C:\Users\<User>\AppData\Local\Razer, and use this command to create symlink to E:\Local\Razer inside C:\Users\<User>\AppData\Local\Razer, so any change in that folder will affect to another location.
mklink /D C:\Users\<user>\AppData\Local\Razer\RzAppEngine E:\Local\Razer\RzAppEngine
Remember to replace <user> with username that installed software, and replace E: to another letter in case you have different drives.
