FortiClient VPN on Windows ARM64 crashes when opening “Configure VPN”

FortiClient VPN on Windows ARM64 – app crashes when opening “Configure VPN” (JavaScript error in Electron process)

Message:
Hello,

I’m encountering a crash issue with FortiClient VPN-only 7.4.3 (ARM64) on Windows 11 ARM64. The application installs and launches properly, but crashes immediately after clicking on “Configure VPN”.

Installation note:
The official installer (FortiClientVPNInstaller_arm64.exe) is an online stub (~5 MB) which does not accept standard command-line switches such as /log, /extract, or /quiet.

To proceed, I monitored the temporary folder during installation and manually extracted the .msi file from the AppData path.
After that, I either ran the MSI directly using msiexec /i or allowed the original EXE to complete. The installation finished successfully.

The application now launches correctly in VPN-only mode.

Current issue:
When I click on "Configure VPN", the application immediately crashes.
There is no visible error message in the GUI.
No relevant logs appear in Event Viewer or standard crash dump locations.

Debug info:
When launching the application from the terminal, the following exception is shown:

A JavaScript error occurred in the main process
Uncaught Exception:
TypeError: Cannot read properties of null (reading 'TraceLog')
at new Logger (app.asar\assets\js\main.js:24121:36)

This appears to be a JavaScript runtime error within the Electron main process, likely due to an uninitialized logging object. The crash occurs before any VPN configuration UI is rendered.

Environment:

• OS: Windows 11 ARM64 (fully updated)

• Device: Snapdragon-based laptop

• FortiClient version: 7.4.3.1790 VPN-only (ARM64)

• Architecture: Native ARM64 (not running in x64 emulation)

Questions:

1. Is this a known bug in FortiClient VPN 7.4.3 (ARM64)?

2. Will a fix be available in a future ARM64 release?
