Question

Updating Fortinet VPN Client from 7.0.5.0238 to latest build

Hi,

 

We are looking to update our fortinet client build to the latest version, we have over 160 devices using the free Forticlient VPN software, after testing we have ran into a issue trying to deploy the latest build via our patch solution in which it is bricking the Fortinet Application completely and no longer loads with the below error, has anyone seen this?

This can be resolved by uninstalling and reinstalling the latest version, however we need to find a workaround as there are over 160 devices with it installed.

 

Thanks

Hi Brad

Why don't use GPO?

    Hi

     

    Most of our users are remote so deploying via GPO will not be the best method for software deployment for us at this time. 

     

    Thanks

    I've come across this same issue recently this week. I tried uninstalling and reinstalling the client as well as upgrading to the latest JAVA version but none of that resolved the issue. Have you been able to come up with a viable solution?

    Hi,

     

    From my understanding there isn't any support around the free Forticlient VPN software, however after some testing it does appear as though its a issue with older versions of Forticlient as pushing the latest executable out to versions that already have 7.0 installed seems to go through okay without the warning above. 

     

     My workaround I have managed to get working is to add in a step in our software deployment tool to remove the application first with script below, and then reinstall the new version, and finally add in our registry keys to add the VPN details back on. 

     

    $Forticlient = Get-WmiObject Win32_Product | Where-Object { $_.Name -eq “FortiClient VPN” }
    msiexec /uninstall $Forticlient.IdentifyingNumber /norestart /quiet
