FortiClient Uninstalled in multiple Windows system

Hi Folks,

I need an urgent solution; we have FortiGate proxy, Forti Authenticator, and FortiClient for SSO in our setup. To deploy FortiClient, we are using SCCM, not EMS. A few days back, we had an issue where FortiClient was uninstalled from many Windows systems-not all at once, but over 2-3 days-and more than 100 users complained. We engaged our SCCM and AD teams, and according to them, there was no trace in the system to identify what triggered the uninstallation. We have taken Fortinet help as well, but as it was not managed through EMS, they said it is not within Fortinet's scope either. However, later we asked the SCCM team to deploy FortiClient again on the affected users' systems and it's working, but we are left with the RCA. Can anybody please help if you have faced such an issue and how we can identify what triggedred the un-installation to prevent in the future.

FortiClient version - 6.0.9
