Hi,

I would like to understand whether FortiClientVPNInstaller 7.4.3.4726 requires version 7.4.3.8758 to be installed in order to fix vulnerabilities.

I’m using ManageEngine Patch Manager, and it says that I need to upgrade to version 7.4.3.8758. However, I cannot find this version anywhere.

Hi

Did you check on the support portal?

It should be found under Download > Firmware Image > FortiClient > 7.4.3.

Otherwise if I’m not wrong I think the latest downloadable FCT VPN “should” already be in the fixed version (build 8758).

Hi ​@Bozzola 

 

Go to the Fortinet support portal and click on firmware download section and select FortiClient as the product list.

 

To install the hotfix locally:
  1. Download the FortiClientTools_7.4.3.8758.zip file from the Fortinet Support website.

  2. Unzip the file and copy the FortiClientTools_7.4.3.8758\SupportUtils\hotfix.exe file to the Downloads folder.

  3. Shutdown FortiClient and run the following installation command in PowerShell:

    C:\Users\ftntt\Downloads>cmd /k hotfix.exe
  4. When the Hotfix 7.4.3.8758 is now installed message is displayed, verify the following:

    • The C:\windows\system32\driver\fortips_74.sys file has been updated (check modification date)

    • The C:\Program Files\Fortinet\FortiClient\resources\app.asar file has been updated (check modification date)

    • The FortiClient version is 7.4.3 hotfix 1.8758 in the About page of the FortiClient GUI.

Thanks, Salon
