It's solved right now. Just reinstalled and cleared the registry.
Sorry 

I'm running Windows 7, there's no domain and I'm the administrator of my computer.
It remembers the favourites list though 

Well, I replaced the Russian gta3.exe with English one, then chose English language.
Thanks for help. You may close this thread.

Each time I start LU, it doesn't remember my nickname and game path.
That's why I have a problem with updating - after the cmd.exe starts, it shows me an error like "The GTA3 path not set". And closes.

So now after the cmd.exe starts, it shows me an error like "The GTA3 path not set". And closes.

Russian language wasn't supported until Rockstar Games establshied its partnership with russian distributor 1C, so this gta3.exe is patched by localiser to support russian (texts and fonts). Patch 1.1 included.
If I use other .exe's, the game won't work.

Hey everybody.

So the problem is stated right in the title, I have got russian-localised by "1C" Grand Theft Auto 3 and Liberty Unleashed installed. Each time I try to enter the game, the error appears:

Incorrect gta3.exe version detected.
You must use GTA3 1.1

But it is 1.1! And it's not cracked!

Here it is. Clicky-clicky. (You must wait 10 seconds until the download starts)

Thanks!
