4 years agoHey @agb95, thanks for reaching out. In most cases this issue is caused by an antivirus or antimalware application preventing 1Password from completing the installation process.
A troubleshooting step that helps determine whether any third party applications are interfering would be restarting Windows in Safe Mode with Networking Enabled and then trying to install 1Password again.
If you're able to successfully install 1Password in Safe Mode, I would recommend excluding both the installation directory at %LOCALAPPDATA%\1Password, and also 1Password.exe from any security software, and making sure both Windows and any security software you're using are completely up to date.
Let me know if this helps!
