Hi,

Can you try to download  FortiClient from Fortinet support page "https://support.fortinet.com/welcome/" another version and test it again.

It happened with me, so I am sharing what I did to solve this issue!

First, ensure you download the latest version of the installer directly from the Fortinet website. After downloading, right-click the installer file, select "Properties," and check the "Unblock" option if available. Next, move the installer to a different location (like your Desktop) to avoid potential permission issues. You can also adjust your internet Options by going to the Advanced tab and enabling the option to allow software to run even if the signature is invalid. If these steps don't resolve the issue, try running Command Prompt as an administrator and execute bcdedit /set nointegritychecks ON. Finally, ensure that your Windows is fully updated, as outdated systems may struggle with newer software signatures. Following these steps should help you successfully install FortiClient without further issues.
