Hello,   Officially no.  It has not yet been certified for ESXi v6.5.  Also there is an issue installing MEM v1.4 w/ESXi v6.x if you are using Vmware Update Manager.    See this thread for an unofficial workaround or use setup.pl instead.  [URL]  I would suggest you wait until either MEM v1.4 is re certified for ESXi v6.5 or a new version is released that does.   Regards, Don  
Does 1.4 work with ESXi 6.5?
