Because of the way, User Account Control (UAC) works in Windows and because Leapwork interacts with the operating system in many different ways, the binaries must be installed in a folder that is trusted by Windows.
Specifically, UAC prohibits typing certain keyboard combinations such as ALT+TAB if the binaries are not stored in a trusted folder.
There are only very few trusted folders, one being C:\Windows\ and the other being C:\Program Files\ (language differences apply). For obvious reasons, the latter has been chosen as the installation folder for Leapwork.
