Right, so I installed 1.5 per these instructions:
This is how I followed the instructions: Copied my BF2 folder to backup drive, patched original. Played it for a bit. Renamed it to Battlefield 2 1.5 then copied back my original Battlefield 2 folder (It is now in the same directory as 1.5 version) I checked my registry value for the version, and it already said 1.4, so I didn't even change that value back.
Why don't it work
Install directory is proper, short cuts I followed have proper directories listed, halp me
Now that I've had enough of the ERYX gayness of Operation Blue Fail, I would like to run BF2 1.4 again. So, after I followed the above directions, I get a CTD every time I try and load BF2 1.4 now!! Yay!!Install BF2 v1.50 Beta 1:
* Copy your Battlefield 2 install to another location
* Install the update
* This will update your version of Battlefield 2 where it was originally installed.
To go back to BF2 v1.41:
* Rename your new (1.50) install folder to something else i.e. Battlefield 2 1.50
* Rename the copied install (1.41) to what it originally was i.e. Battlefield 2
* Click START>RUN
* Type: regedit
* Go to (in Vista its different): HKEY_LOCAL_MACHINE\SOFTWARE\Electronic Arts\EA GAMES\Battlefield 2
* There you will see a key called Version. It should say 1.50
* Change this to 1.40 and close regedit
* Run Battlefield 2 as normal
