FortiClient VPN - Stuck on "Connecting"

[JPL-Safari]

Installing 7.4.0.1658 on two different Windows 11 (Dell Vostro and Dell Inspiron) Laptops.  Both laptops were Wiped and Prepped with the same Windows 11 23H2 Pro OS and are set up using very basic Intune Profiles (Intune barely does anything).

The VPN Client, when launched, only goes as far as "Connecting".  It never times out and appears as if its stuck.  

Are there any Windows Settings I should be looking at which would impact the clients ability to establish a connection?  Logs dont appear to show anything indicating the VPN is even attempting to connect.

Updating the client is was caused this issue. Reverting back to older versions of the client is what's fixing the issue of the client being stuck on "connecting".

Dear Pavan,

Whatever you suggested already had been tried before this comment. BUT now the issues is the newest update caused the connection problem bug. Do you have any other solution?

I'm running into issues on both the latest Windows 10 and Windows 11 with FortiClient VPN 7.4.0.1658.  We just recently cut from an older Cisco ASA and have run into the stuck on "Connecting" bug with a few different laptops and desktops. Uninstalling 7.4.0.1658 and installing 7.2.4.0972 seems to be the fix for those PCs for now.  I understand it's an "unsupported" application but I think this needs some support from the developers.

The FortiTray.exe app is missing a .dll file. That why it's stuck on Connecting.

Download and install the 2 Visual Studio Redistributables from this topic: DLL files missing after Windows 11 update - Microsoft Community

After that your FortiClient should be working again.

As AGU_HD mentioned, mfc140u.dll was missing from Windows 11.  After installing MS VS C++, the FortiClient application began working again. 

Please try to download and install both x86 and x64 versions of the multi-installer Visual C++ 2015, 2017 and 2019 redistributables. Restart your PC after the installation. Note: Don't install the ARM64
