These patch files can be installed using the Web-based front-end of NetYCE.
From the Admin menu select System. The System status tool is activated by default.

To get to the NetYCE update section, check the box Full report and click on the server-button to be updated. In the resulting page, scroll down to the YCE software section where the button labeled Install YCE distribution can be found.

Drag the downloaded installation image (eg YCE_6.0.0_20140812.bin) over the Choose file button or select the file after pressing it). Then press the Install YCE distribution button.

Patiently wait until the install file gets uploaded, installed and the System page is completed. The install can take about a minute.
