Help with changing language and the launcher

[Heodez]

Yep, you read well, this is a cry for help. This is quite a technical question so I thought I'd turn to you even though... well, this is Maty.

So, I bought the game in French, but it was so horrid that I changed the language to English with regedit. So far so good, the game works fine. (no EP/SP, latest patch)
Thing is, now the launcher won't start, and I need it to install sims3packs. Now, to install them, I have to regedit back to French, change "My Documents\Electronic Arts\The Sims3" to "My Documents\Electronic Arts\Les Sims3" just for the launcher to work, and then do it all back again to play in English.

My question is, do you know how to fix the launcher so that it will recognize my English set up?

Why are you using the launcher?

[Heodez]

I said it: to install some sims3packs. The 3viewer doesn't always work, so I resort to the launcher.

You could always just torrent a multi-language version and select English when you install it.
