BF2 Multiple Install Instances

**ZaBoo** · 08-21-2008, 07:51 PM

Hey guys,

I've had problems getting mods to work simutaniusly with vanilla bf2 which others in my house play every once in a while. Some mods modify your vBF2 content and won't allow you to play! Here are some rough instructions to get two instances running at once. I have attached a sample for project reality. You would have to modify it for other mods.

Rename your ...EA GAMES\Battlefield 2\ folder to ...EA GAMES\Project Reality\
Uninstall battlefield 2 (Keep your profile data!!)
Install BF2 + the latest patch

At this point you have two copies of battlefield on your harddrive.

...EA GAMES\Battlefield 2\
...EA GAMES\Project Reality\

Now we need to create some quick scripts to switch between them. Please note directory paths will need to be changed, as well as the registry paths, and shortcut options. (I am using +szx 1680 +szy 1050 for widescreen)
Can someone please post proper registry paths for a non x64 bit machine?

..EA GAMES\fixbf2.reg
(Changes the registry to point the the ...EA GAMES\Battlefield 2\ folder)

Code:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Electronic Arts\EA Games\Battlefield 2]
"InstallDir"="D:\\Program Files (x86)\\EA GAMES\\Battlefield 2"

..EA GAMES\bf2.bat
(Launches the registry fix, and launches ...EA GAMES\Battlefield 2\BF2.exe)

Code:

REGEDIT.exe /S fixbf2.reg
cd Battlefield 2/
start BF2.exe +menu 1 +fullscreen 1 +szx 1680 +szy 1050
for %%v in ("prompt $e[m" "echo on" cls) do %%v

..EA GAMES\fixpr.reg
(Changes the registry to point the the ...EA GAMES\Project Reality\ folder)

Code:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Electronic Arts\EA Games\Battlefield 2]
"InstallDir"="D:\\Program Files (x86)\\EA GAMES\\Project Reality"

..EA GAMES\pr.bat
(Launches the registry fix, and launches ...EA GAMES\Project Reality\mods\pr\pr.exe)

Code:

REGEDIT.exe /S fixpr.reg
cd Project Reality\
start mods\pr\pr.exe +modPath mods/pr +menu 1 +fullscreen 1 +szx 1680 +szy 1050
for %%v in ("prompt $e[m" "echo on" cls) do %%v

Then, just create shortcut's to the *.bat files on your desktop!

Attached is a zip of my sample files.

Best of luck!

I have a question. so after creating and modifying the registry files and running them, I have to use the batch file to start second instance of battlefield 2 and start first instance normally using desktop shortcut?

I understand the instruction completely but I'm not sure how I would go about running two instances.

and obviously, I have 2 cd-keys.

This is two have two seperate installations. I don't think you can run two instances at once.

damn... I've heard that it's possible but I could never find working method

I use to do something similar to this with different versions of the BF2. Such as v1.0 and v1.41. I use to play BF2 on a server that ran only v1.0 and I loved playing with the guys there but also loved playing some of the mods that required updated patches such as PR.

However I did not know you could put everything into one shortcut to start up at once, I had 2 separate registry entries saved on my computer and before playing a certain version I had to merge the registry entry over and then click the shortcut to play BF2 or whatever mod I wanted to.
