1. Make sure you have installed PR MP v0.75 and the maps before you install PR SP v0.75

2. If you have already installed PRSP v0.708 and have a folder named pr_sp_07 rename that folder to something like pr_sp_07_old
NOTE: There is no need to make a copy of your pr folder anymore.

3. Use the Installer and make sure it is pointing to C:\Program Files\EA Games\Battlefield 2\mods\pr_sp_07
NOTE: If you have your BF2 installed in a different location then make sure it is pointing to that location
(e.g. H:\Battlefield 2\mods\pr_sp_07)
The installer will make a new folder called pr_sp_07 and install the correct files for PR SP v0.75

4. Copy your levels folder from the pr folder to the new pr_sp_07 folder and then copy the levels folder from your pr_sp_07_old folder to the new pr_sp_07 folder (this will save you having to download the map packs again)
NOTE: If this is your first time installing PRSP you will have to copy your levels folder from pr to pr_sp_07 and then download the PR SP Map Packs and install them seperatly.
Also when installing the mappacks make sure you have the path pointing to your mods folder and not mods\levels as the installer will find the levels folder for itself.

5. You also need the init.con pack that will update all the maps to PR_SP_075, inside this pack you will find all the new init.con's inside folders named after the maps.
NOTE: These new init.cons puts the officer kit in the correct place (#1 slot) and also makes the officer kit work correctly i.e. you can set Rally Points with it.

To install these init.con's is very easy..... here's what you have to do.....
Double click on the Init.cons_075.rar and open the map of your choice, inside you will find the init.con for that map.
Next go to your pr_sp_07\levels folder and open the map of your choice, inside you will see a server.zip double click on this file to open it.....
now just drag the init.con from the Init.cons_075.rar into your server.zip.... do the same for all map folders that you have.
NOTE: The new Map Pack 7 already has the new init.con's included.

6. This Installer will also make a shortcut on your Desktop and in the Start Menu and point to the default install path ("C:\Program Files\EA Games\Battlefield 2\mods\pr\pr.exe" +modPath mods/pr_sp_07 +menu 1 +fullscreen 1)
NOTE: If you have your BF2 installed in a different location make sure the shortcut is pointing to the correct path in the Target box and Start in box (do this by right clicking on the shortcut and going to properties)

Thats all there is to it....... enjoy
