Install the VMware Horizon 8.x setup, and the installation will go smoothly. Perform a reboot on the broker virtual machine, and this step will delete the services from about that were not getting deleted automatically. The quick solution is to uninstall the VMware Horizon 7 HTML Access, followed by VMware Horizon 7 Connection Server. The core reason for the in-place upgrade failing was that the VMware Service around Horizon was not getting deleted during the uninstall performed by the setup, which was rolling back the change.

In this post, I will go into the details on the manual uninstall process and installation of the latest version of the VMware Horizon. In my previous blog post Upgrade from VMware Horizon 7.13.1 to 8.6 (2206) fails with VMware Horizon View Blast Secure Gateway (VMBlastSG) could not be installed.
