Go into the shortcut's properties and edit the Target box so that at the end of "C:\Program Files (x86)\Electronic Arts\The Lord of the Rings, The Rise of the Witch-king\lotrbfme2ep1.exe" there is -mod "location of your aotr folder inside Age of the Ring 7.0"Į.g.
Create a shortcut from the lotrbfme2ep1.exe file in your vanilla RotWK folder.
Open the aotr.zip included in the downloaded AotR_Version_7.0.rar and extract all of its contents into the folder you have created.
Create a folder named Age of the Ring 7.0 in an installation location of your choice (e.g C:/Program Files/Age of the Ring 7.0).
If you are experiencing issues with the installer, it is possible to manually install Age of the Ring 7.0:
The installer creates a shortcut to AotR 7.0 on your desktop.
Run AgeOfTheRingInstaller.exe (if it doesn't work, run the installers as an administrator).
Unzip the contents of AotR7.0.zip into a folder.
Disable the timer and the 2.02 music options.
Open the patch 2.02 launcher (found in RotWK's installation folder) and make sure it's enabled.
To play Age of the Ring, either don't update to the latest 2.02 version or use the 2.02 launcher to set your Rise of the Witch-king to v8.0.1.
Install patch 2.02 - make sure to download the full version.
