I downloaded the EXXi 4.1 Build 381591 Dated 4-28-2011, per an E-mail notification from VMWare, and I am having problems installing and not updating my Server.I ma using Vsphere Client and doing this via the Command Line. Using vihostupdate.pl returns "Operation not supported on 4.1.0". Also tried "remoteinstall.exe" which this patch zip file does not seem to have. Please let me know the Syntax that I need to do to upate this server? Thank you.
