Removed ONLINE GAMES. How to reinstall them?

[Aquax]

I removed ONLINE GAMES with nLite, but "normal" games remain.

Now I need to use an ONLINE GAME, so I extracted files from the xp cd. But I get an error that says I have to Reinstall it from the Control Panel.

I cannot do that, because I removed them with nLite.

Is there a way to get back OnLine Game work????

Thanks
