Unable to install FortiClient VPN

[hztm]

Trying to install the FortiClient VPN from https://www.fortinet.com/support/product-downloads keeps showing this error. I'm on Windows 11 22H2

Same today also, something is up on Forticlients side.  Over 10 download attempts with multiple reboots and cache clearouts inbetween but still encounter the same issue as you report.  

Looks like they have something to fix, and in the meantime, unless you have the offline installer - You aren't going to be able to get it going.

Unfortunately I don't have access to the offline installer.

We are seeing this also. Currently trying to download the offline installer to see if that works but the 150Mb which should take a few seconds is taking 25 minutes to download. Is this always the case with fortinet?

[JayJohnson]

Nope, seems to be something new.  Very slow, often failing claiming corrupt, the other times it is declaring as above: The digital signature is invalid.

I also find today, one of our SSL VPN connections is providing error code=-100 (v1.0.1041)

All of the above appear to be new, I have been using FortiClient products for a year now.

Hi @hztm,
If possible, please download the firmware from support.fortinet.com. There seem to be issue with online installer.

Can you share the offline installer with me?

Hi @paperino95,

Unfortunately, you need to login to your account and download. Or you can open a ticket with TAC and we can help you with that.

Having the same issue with two different 22H2 machines. Anyone has access to offline installers?

Thanks.

I have successfully installed the online installer after attempting to do so again.
Because for the offline installer, aside from the need for an account I think you also need the license of the product/support
