Ok I successfully installed FortiClient in my VMware Workstation.
I went through all of the installers available and they all will install "FortiClient". The Lite and Standard versions have magically disappeared without any notifications. Nothing mentioned on their website or forums. They didn't even notify third-party download sites.
You go to download the Lite or Standard and get something else from the online installers. I'm thinking that they have discontinued the Lite and Standard editions and now just make one complete suite just called FortiClient. I guess the only way to find out is to call their support- http://www.fortinet.com/contact_us/index.html . FortiNet has never tried to market their products to home users except for the Lite edition which probably wasn't that successful, even though it was an excellent product. They sell their products to businesses mainly large companies. Therefore they don't seem to care about posting updates for home users but will allow home users to use FortiClient for free without any support.
The current version is 5.0.3.246, I did not give it a complete test run, but it appears to be running smooth in VMware using Windows 8 32-bit.
I didn't notice any decrease in browsing speed using IE10. I ran 15 of the latest malicious url's from Malware Domain List using IE10, SmartScreen blocked all but one of them before FortiClient could get a chance too. The other was blocked by FortiClient. It is a very powerful suite maybe the best since it doesn't seem to have any compatibility problems. However it is for users who have time and want to learn how to configure it. Kind of like Comodo Internet Security Suite but works differently. CIS mainly relies on HIPS and sandboxing whereas FortiClient relies on url proxy filter and application firewall. Its url proxy filter is so good that it is unlikely you would ever need to use the AV module or other components except for the Vulnerability scan. However it is not for novice users or users who just want a simple AV. It is made to be an Endpoint solution for businesses.
I didn't really expect SmartScreen to do that good. However with SmartScreen disabled FortiClient successfully blocked all of the latest 15 malicious links.
Enjoy!!
