To install, simply EXTRACT everything from the zip file to a desired location, and run the Ego ERP Archiver.exe file.
This program lets you export and import resources from ERP archives for EGO engine games. Resources include various xml, pkg, and texture files.
After turning on the program simply click File -> Open and select a ERP file. When importing resources make sure to select the same folder that you exported into. The program will search for the same exact resource folder and file name as when the resource was exported.
If you have F1 2016 and newer, make sure to set the directory from the Settings menu. Some textures in this game have mipmaps counterparts that get exported into a single dds. When importing these textures, you will be prompted to save a new mipmap file. Changes are made to the texture inside the erp during import as well, so make sure to save your erp file too.
