VMware Composer Install Fails

KB ID 0001498


While attempting to deploy VMware Composer, (in my case version 7) on a windows Server, (in my case 2016 Datacenter). This happened;

Composer Instllation Failed

Installation Failed

The wizard was interrupted before VMware Horizon7 Composer could be completely installed.

Your system has not been modified. To complete installation at another time please run setup again.

Click Finish to exit the wizard.

Annoyingly I know what it was straight away, because I’d read up on the subject before I started. 


‘Power Off’ the server, locate its VM > Edit Settings > VM Options > Boot Options > Ensure firmware is set to “EFI (recommended) > Note: It should be by default > Under Secure boot ‘Untick‘ Secure boot (EFI boot only) > OK.

Composer Server Disable Secure Boot

Power the server back on, then retry the VMware Horizon Composer installation.

Composer Server Installed
