When you are finished adding mods from the modpack, just click 'cancel' to exit out of the prompt loop. This will extract the archive and prompt you to choose the folder of the mod that you want to add. To install a modpack, check the 'Modpack' checkbox when choosing a name for the mod you are currently adding. This only supports mods that use modengine compressed in a RAR, Zip, or 7z format. This is done by changing the folder modengine uses in modengine.ini. Just install whatever profiles you plan on frequently using, then choose the profile you want to enable in the combo box and click 'set active'. Another advantage of using profiles is that you dont have to overwrite anything when installing a new one. Just click the 'plus' button, specify the name of the profile and how many mods will be included, then choose what mods to add. You can make a mod profile which contains both mods. Lets say you want to have the Boss Rush mod, and have a cosmetic mod for sekiro you also like. This will unpack the mod files into the into the mods folder in the sekiro directory(provided modengine is installed). To install a mod, first add it to the manager by pressing the 'plus' button, then press the install button. Im pretty sure you only need the 2015 version, but if it doesn't work then install the 20 versions. In addition to modengine, you need the Microsoft Visual Studio C++ Redistributables found here .
