No indication when launcher fails to create directory

I have some older profiles that are set up to use a different username (from an older PC), which use the wrong game directory. It has an invalid username on it, and the launcher can't create the new user folder (because C:/Users/ doesn't allow it). This is entirely logical.

However, when the laucher does this, it doesn't abort the launch visually, although it does output info to the console.

[14:47:16 ERROR]: Aborting launch; couldn't create game directory

The problem here is that it looks like it's just taking a long time to launch, while in reality it has aborted the launch. It also keeps the "Launch" button disabled forever (IE, until closing and reopening the launcher).

I expected the launcher to fully abort the launch (as it does when it cannot download a version) and switch to the logs tab.
