If you get errors in the middle of installing the patch, or you have issues running the game, restart your PC and try to install the patch again with default settings.Solutions to common issues with the patch You can remove the downloaded patcher files now if you want to save some space, but it's recommended to keep them in case you need to fix your game in the future. Done! You can now start the game launcher as usual and you will notice some new options straight away.
The default settings should work well for most users.
The patch can and will remove and overwrite some files and directories (except for UserData, that folder is always safe). Freely available R18 patches are included, you don't have to install them manually (but doing so won't hurt anything). You don't have to install all of them, you can pick only some DLCs or not install any DLCs at all. For more detailed info check the GitHub page of your patch. This is a general overview of the installation process.
