Error code 1625 means "This installation is forbidden by system policy," which occurs when Windows security settings, user account control policies, or antivirus software block the installation. To fix it, you can try running the installer as an administrator, adjust local or group policies, or check for and remove any revoked certificates under the "Untrusted Publishers" tab in Internet Options
