First off... Welcome to the forums and the community!
Second... it's Georgia not Gerogia.
All I can do is direct you to the Installation Guide:
https://www.realitymod.com/forum/f27-pr ... guide.html
Straight from the guide:
4) Download the TWO seperate Project Reality 0.856 Client Installers from your preferred URL/torrent from the realitymod.com Files Page
The two installers are listed as CORE and LEVELS.
5) Run the CORE installer, following the on-screen prompts to accept the licence agreement and path of install. Unless you have installed BF2 in a custom folder (ie - not the default path), you will not need to choose a different path other than the one listed in the installer. We recommend changing the 'CUSTOM INSTALL' to 'COMPLETE INSTALL'. Choose if you want to have a desktop icon installed, then click 'Finish'.*
6) Run the LEVELS installer, following the on-screen prompts to accept the licence agreement and path of install. Unless you have installed BF2 in a custom folder (ie - not the default path), you will not need to choose a different path other than the one listed in the installer. We recommend changing the 'CUSTOM INSTALL' to 'COMPLETE INSTALL'. Choose if you want to have a desktop icon installed, then click 'Finish'.*
* It is recommended that you restart your system after you install/uninstall programs to ensure all installed components, files and registry entries are correctly installed or removed.
7) Enjoy the mod! We hope you enjoy playing the mod as much as we enjoy creating and playing it!
