Start FortiClient VPN ERROR JavaScript on ARM64 System

[Sylatex]

Hi,
After installing FortiClient (FortiClientVPNSetup_7.4.3.1790_ARM64), it worked great.
After a week, I can no longer start FortiClient.

I've already uninstalled it and tried FCRemover.exe.
Nothing helped.
What's the problem, what can I do?
Regards, Martin

Hello again Martin,

I found this solution, can you tell me if it helps you, please?

To address the "A JavaScript error occurred in the main process" issue with FortiClient on Windows 11, follow these steps:

1. Check Compatibility: Ensure that the version of FortiClient you are using is compatible with Windows 11 ARM64 architecture.
2. Reinstall FortiClient: Uninstall the current FortiClient using the standard Windows uninstallation process. Download the latest compatible version of FortiClient for ARM64 from the official Fortinet website and install the downloaded version.
3. Clear Cache and Temporary Files: Use the Disk Cleanup tool to clear temporary files and system cache.
4. Update System: Ensure that your Windows 11 is up to date with the latest patches and updates.
5. Check for JavaScript Errors: If the error persists, check for any JavaScript-related issues in your system that might be causing the error. If the problem continues after these steps, consider reaching out to Fortinet support for further assistance.
