Antivirus Software
Update your antivirus software (AV): Ensure that your AV is up to date with the latest virus definitions and software updates. Sometimes outdated AV can cause false positives. This will most likely require speaking with your internal IT.
Alternatively, you can try temporarily disabling your Antivirus.

Some Virtual Private Networks (VPN) will interfere with the installer working correctly. If you have one, try disabling it and then running the installer again. Disabling it will vary depending on what VPN you are using. Refer to your VPN's documentation if you are unsure how to do this.
