Synpase 3 Install fail code 145 | Razer Insider
Skip to main content
Had Synpase 3 before but needed update, the updated didn't work properly and wouldn't start up again. I uninstalled it and deleted all razer files from laptop. Went to install newest version found on website and now its failing the install at around 20% and showing code 145. How can I fix this?


  • 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).



Also check for any Windows updates - if there are any - update them. Check if .net redistributables are in the newest version - if not - update them.



You can also disable antivirus and firewall when installing Synapse - they also may cause interruptions.
Done all the above, and still same error.
