Unable to install FortiClient VPN 7.4.3 Win Arm

[saki]

Hi,
I was so hyped that arm version of FortiClient was finally released and asked network admin to send me FortiClientVPNSetup_7.4.3.1790_ARM64.exe , but installation always fails :( 
Installation log where it fails:

System Information:

Operating System: Windows 11 Pro 64-bit (10.0, Build 26100)
System Manufacturer: Dell Inc.
System Model: XPS 13 9345
BIOS: 2.5.0
Processor: Snapdragon(R) X Elite - X1E80100 - Qualcomm(R) Oryon(TM) CPU (12 CPUs)

I am the only one in the company using Windows and ARM compatibility doesn't help me, so I would be grateful for any help in solving the problem :folded_hands:.

***FIX***

Here is another solution that worked for me.

Go into: C:\Users\Administrator\AppData\Local\Temp

Delete Everything.

Then, run the ARM64 installer you can download from Fortinet

When the installer "ends prematurely", go into the same Temp file, find the folder FCT_{...}

Next, give admin access to Forticlient.msi and install it. It should install this time and work after restarting.

Hope that helps!

Hello,

you must use the msi installer version, not the exe.

I've got an XPS 13 9345 and the installation worked with the msi

Hi,

Had the exact same issue on my laptop (arm64, Snapdragon X processor) but managed to fix it by clearing out all folders in C:\ProgramData\Applications\Cache, specifically anything containing FortiClientVPN.msi.

After doing that, the online installer was still being stubborn, but the offline installer worked perfectly.

This thread was super helpful for resolving this annnnnnoying issue. Thanks fr!
