The purpose of the LotR:O Plugin Assistant is to simplify the installation and management of LotR:O plugins. It’s designed to accommodate users with no prior experience with plugins. The primary goal of the program is to automate the process of installing plugins. However, the program will also install the necessary Turbine support files if they are missing and allow users to enable or disable plugins as well as delete them entirely.
Say, for example, you download a plugin file and save it to your desktop. All you need to do is run the LotR:O Plugin Assistant then drag and drop the plugin file you downloaded into the LotR:O Plugin Assistant's Plugin list. That's it. The program will examine the plugin and install it to the right directory without user intervention. The plugin will be ready for use in game.
The LotR:O Plugin Assistant can only assist with matters outside the game. While it can greatly simplify the process of installing plugins it will not make them any easier to run in the game.
The LotR:O Plugin Assistant makes use of the 7z.exe executable file for it's file decompression needs.
