--- Comment #3 from Damjan Jovanovic damjan.jov@gmail.com --- It looks like some sort of font issue, as "winetricks -q allfonts" got it working.
Even so, the fact a missing font is now breaking an installer this badly is a serious functional regression, that may affect many more apps. At the very least, we should print an error with the missing font name, before the app hangs in an infinite loop.
