Forticlient fails to install Deployment package from EMS server



I'm currently setting up FortiClient EMS 7.0.11 on a ESXI VM (win 2022 server), performing a unattended deployment using both FortiClient 7.0.11 and 6.4.10 to a windows 11 machine as well as another windows server 2022. None of them are being launched/installed on these Domain joined machines, logs on EMS are showing "xxxx deployment state 150 - Deployment error" for all endpoints


I have gone through the process of ensuring that none of my issues match the link below


All services have been applied through GPO, inbound firewall rules added. EMS can communicate with the machines using their hostnames, 



Firewall rules




So Connectivity/firewall/services aren't an issue

Wireshark shows that there is definitely communication between the EMS server and my windows 11 test client


WIN11 -



win11-EMS.PNGI've also tried to install FortiClient on the server where EMS is running and this is also failing here too,


Are there any logs that I query that would get me information on the actual reason why it is failing and not just the generic "150" error message?


Thanks in advance

Hello @H2 ,


I know what I said is not the solution. I want to advise you about your problem.


I think you shouldn't use EMS as a remote deployment app. Because it has a lot of variables and problem-solving is not easy. Also, Fortinet removed this feature in version 7.2.


In my opinion, if you have a remote app deployment solution like an SCCM, SolarWinds, etc. (You can use MSI package created by EMS). You can use these tools for deployment after that you can manage your FortiClient upgrade or downgrade process with EMS without any problem.
