Getting the Apple/QuickTime AAC encoder ready involves *two* separate steps: In the first place we will install the QAAC encoder, and in the second place we will install the Apple AAC encoder libraries.
+
#### Install QAAC Encoder ####
First of all, you need to download the [QAAC](https://github.com/nu774/qaac) application, which provides a CLI font-end to the Apple/QuickTime AAC encoder. QAAC is provided as an *Add-in* for LameXP and is available from the following locations:
Now open the downloaded ZIP file, e.g. ``LameXP.qaac-addin.yyyy-mm-dd.zip``, with your favourite file archive software (we recommend using [7-Zip](http://www.7-zip.org/) or [WinRAR](http://www.rarlab.com/download.htm)) to find the required QAAC program files.
-*Note:* The LameXP software generally expects the **latest** version of the QAAC add-in; and the QAAC add-in is designed to work with the **latest** version of the LameXP software.

#### Install Apple AAC Encoder Libraries ####
Next, the actual Apple/QuickTime AAC encoder libraries, which are part of the so-called "Apple Application Support" package, need to be installed on your computer. QAAC can *not* work without these libraries!

+After the "Apple Application Support" setup package has been extracted, launch the installer by double-clicking on the ``AppleApplicationSupport.msi`` file and follow the installer's instructions.

+Once the QAAC encoder as well as the Apple AAC encoder libraries ("Apple Application Support") have been installed properly, simply *restart* LameXP in order to enable the AAC encoding support!
