When you start windows the 2020 Fusion Background.exe will launch automatically to continue processing any background prints, exports, 360° Panorama's, movies or renders you have instigated. In addition to this, when you launch 2020 Fusion the OnlineTransferTool.exe will initiate to check for any uninstalled catalogue updates. Both of these can result in the error message below when trying to run a 2020 Fusion Update Installer.
As of version 8 the notification pop up has been improved to display what processes are preventing the installer from running.
