To avoid an untrusted search path vulnerability where users could gain increased privileges, perform the following additional steps:

    1. Clear all contents (files, sub-directories and etc.,) of your default download directory/location, if any.
    2. Create a new secure directory in temporary location (such that elevated privileges are required to access this directory).
    3. Copy/extract the setup.exe executable to the secure directory created in Step 2.
    4. Launch the executable from the secure directory and wait until it completes.
Important: Do not enter line breaks in the command that you enter to start the installation program.
