Forticlient VPN Only Installer 7.4.3.4726

Hi,

We deploy the FortiClient VPN Only app using the MSI installer, which the FortiClient Online Installer exe (7.4.3.4799) downloads into C:\ProgramData\Applications\Cache\GUID\7.4.3.4726\FortiClientVPN.msi.

This MSI has the same product code {15C7B361-A0B2-4E79-93E0-868B5000BA3F} as our previously deployed install (7.4.3.1790), which prevents an in-place major upgrade, as the Windows Installer thinks it is already installed.

Could you please rectify the latest MSI so it uses a unique product code? This was never a problem until now and is impacting our ability to deploy the newer client to machines running an older FortiClient version, leaving them susceptible to vulnerabilities.

Regards

Toji
