2025-10-12T02:17:23.24+00:00 Remove any existing FortiClient installations via Control Panel.
After uninstallation, manually delete any remaining FortiClient files from: C:\Program Files\Fortinet and C:\ProgramData\Fortinet.
Download and install Microsoft Visual C++ Redistributables
Disable any AV.
Review the Windows Event Viewer logs related to this.
Right-click the installer file and select Run as administrator.
