  1. How would i go about installing this on my 4th Gen intel nuc? I currently have 6.5.0 (Build 4564106) installed.

  2. The provided download link for the 6.5 U1 Hypervisor does not allow registered free users to actually download. Upon login you are met with the error: You either are not entitled or do not have permissions to download this product.

    The separate "free" link on VMware's site at https://my.vmware.com/en/group/vmware/evalcenter?p=free-esxi6 still only provides version 6.5.0a.

    Where can one actually download the 6.5 U1 installer ISO with a free license?

    • I have the exact same problem. Created a support ticket to get an answer.

    • You can always install 6.5 *whatever-older-version* and update to the latest version, or use PowerCLI Image Builder to create a "custom ISO".
      I know, that's not a 100% answer, and a downloadable ISO is nicer, but it definitely works allows you to use the latest ESXi version.

    • Here you go with PowerCLI for the latest version ISO:

      PowerCLI C:\esx> Add-EsxSoftwareDepot https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml
      PowerCLI C:\esx> Export-ESXImageProfile -ImageProfile "ESXi-6.5.0-20170702001-standard" -ExportToISO -filepath ESXi-6.5.0-20170702001-standard.iso

      Or upgrade your box:

      esxcli software profile update -p ESXi-6.5.0-20170702001-standard -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml

  3. Do we need to update the vCenter first to 6.5U1 before updating the host to 6.5U1 from 6.5. Is there a co-relation between their build version even though both running on 6.5?
