E {PKG Installer} LDR: Not a PKG File!

I want to install game in rpcs3. but, when im select the .PKG files and going to install it. Small windows appear says "Another installation found. Do you want to overwrite it?" I don't know what happen, im never installed this game. it's my first time using rpcs3. When i click on "yes" button, Red collored messages appear on the log box. it says " E {PKG Installer} LDR: Not a PKG File!"

If you know the answer please help. and sorry for bad english

Million dollar question: is the file you're trying to install actually a .pkg file?

You can also install it on a CFW PS3 and transfer the already unpacked game to your computer. But pkg installation is indeed working, you're doing something wrong.

Maybe the file is corrupted? Like a bad download/transfer or something.
