7.1 RAZER SURROUND SOUND - ACTIVATION CODE

Good evening, I had been used my account for a long time where was linked with my headphones Razer privileges on software "RazerSurroundInstaller2.0.29.20.exe", but it seems is not working well with windows 10 and it makes some continues interferences. I tried everything to fix it but the only solution it seems to format everything and start from begining, no way so I decided to update with new software for surround purposes. I just downloaded new version which maybe fix this issue "7.1SurroundSoundInstaller_V1.0.112.145.exe" but when I submit my data, it's asking me for activation code, headphones had not this code or yes due to I can`t see it. On my others devices like keyboard and mouse, you can read the code clearly. Please let me know how to obtein above metioned activation code due to I have no headphones boxes any more, but keyboard & mouse. Many thanks in advance for your attention and good comments. Best regard
