instalation is in russian, but u can choose english like in icq 6.

But the language can be changed only after installation. And in other countries for example Germany you probably can't sign in, so the language code has to be modified.

I already created a banner remover for this version last week. I hope it could be published the next days.

The official link is install_icqlite.exe 9.16 MB (9,612,176 bytes), but there's also install_sicqlite.exe 9.16 MB (9,608,944 bytes) in the pub. So what's the difference there, can anybody say? o.0

I can't see any difference.
