I got 2 Razer gold cards at target for a friend so I needed to scratch the card and send them the picture of the card and I mistakenly scratched off some codes of the card so I need help with the complete codes so I can send to my friend who needs the card 

Uninstall Synapse
Download & run this tool: https://rzr.to/Tf53xj to remove any razer drivers/leftovers
Then restart your PC
After reboot install Synapse again (as administrator).
