As already said, you can't change that name, because (I guess) it's implemented in the quellcode of the launcher, and once compiled you can't really change it.
Only possibility would be to code a completely new launcher, but this would take some time, and I guess you won't want to rewrite the launcher. Besides the coding, the other problem would be, that ...nah, whatever, it's too much work for changing ONE name.

have a nice day, sir.
