To enjoy the 8.52 that posted here, try to install trial version of 5.2, open the trial version, download all the contents through content manager, then uninstall it.
Next, install 8.4 or any version you have, just patch it with 8.4, now patch it with your new 8.52.... you will get everything working including all contents. thank you all, thanks to Dev3d, thanks to Zonegfx Team. more blessings.
