Feature transfer error: Access is denied

Problem

A friend of mine was trying to install the EMTrade program on Windows 8.1. He was logged in as a standard user, but when the installer asked for administrator permissions using User Account Control (UAC), he provided the login and password of an administrator account. The installer proceeded to install, but failed while creating the C:\Program Files\Emkay directory, with this error:

Feature transfer error
File: C:Program FilesEmkay
Access is denied

Solution

A few old installers for Windows still struggle with UAC. The EMTrade installer worked fine when I explicitly switched user, logged into an administrator account and installed from inside it.

Tried with: Windows 8.1
