BF2142 how to downgrade patch from 1.5 to 1.4

On a PC, I guess?

1° uninstall your game

2° do NOT go to regedit. NEVER. Unless you are an experimented Winsh*t Guru

3° purchase Registry Mechanics (http://www.pctools.com/registry-mechanic/) 29,99 € sorry for that

4° run regmech, this will remove in the registry ALL data from an already uninstalled program

5° reboot

6° delete the Origin Games folder in the Program Files directory (do NOT delete the Origin folder or you'll have to reinstall Origin)

7° reinstall the game, should do it.

Unless you start deleting things randomly in regedit not much can go wrong if you follow proper instructions. Just a basic windows knowledge will do.

Your stats are saved online. So no need to worry about that.

I do not own BF2142 so I can only help so much. How do you install the game, with a cd or trough Origin? Origin might already install the latest version of the game.

Uninstalling the game and running a registry cleaner is always a safe way. Instead of buying a overpriced product http://www.filehippo.com/download_ccleaner/ should work just fine.

Otherwise the registry might again be a solution, but because I do not own the game I cannot give a precise discription:

If you follow these instructions and reach step 10, instead of deleting the folder look on the right side. See if you see a key with the name of something like 'version' with the value of 1.5. If you see that and change it to 1.0 the patch might install properly.
