--- Comment #74 from jre.winesim@gmail.com --- Found in 1.7.45 (Debian's wine-development 1.7.45-1) with SteuerSparErklärung 2015 (free test version available, see AppDB link):
Start the installer, choose "Express-Installation", tick "Testversion installieren". In the view of the "Lizenzvereinbarung" (which is not displayed as reported in bug #37743) click "Drucken" (Print) --> The installer ends up unresponsive and continuously emits the line fixme:richedit:ME_HandleMessage EM_FORMATRANGE: stub
"winetricks riched20" solves this.
