Not meaning to offend anyone, but the phrase "It's only a Patch so make sure you have run the full install before (the 500 mb file).", with the words 'Full Install' leading to a download, seem rather explicit to me. On top of that, the term 'patch'
never stands for 'Full install, install me and you're done!'.
I get the same issues with people installing RifE, even after I give VERY detailed installation instructions; Honestly, the only way you'll know it's installed correctly is if you read the full post. Not just click the first link you see and hope for the best.
